MEETING DATE: AGENDA #: PREPARED BY: DISCUSSION: HISTORY In May of 1997, Scott and Dakota Counties in conjunction with MnDOT and the Metropolitan Council began a Corridor Study of County Highway (CH) 42. The study area entailed. the length of CH 42 from TH 169 in Shakopee on the western end to TH 55 in Rosemount on the eastern end. The impetus for the Corridor Study was the increasing pressure on the counties from the cities to provide increased access directly to CH 42. The report was presented at the joint City Council/Planning Commission meeting.. on November 30, 1998. The participants in the Corridor Study include Dakota and Scott Counties; the cities of Shakopee, Prior Lake, Savage, Burnsville, Apple Valley, and Rosemount; MnDOT; the Metropolitan Council; and the consulting firm BRW. The final draft study contains eight chapters as follows: 1. Executive Summary 2. Introduction 3. Public Participation 4. Preliminary Technical Analysis 5. Systematic Development of Solutions 6. Detailed Traffic Operations Analysis 7. Environmental Overview 8. Recommended Corridor Implementation Plan The Executive Summary, copy attached, briefly provides further information about each chapter. In general, the following steps were conducted in the process of the study: conduct technical and operational analyses of the corridor; achieve consensus about findings of fact from these analyses' achieve consensus about the 16200~ Creek Ave. S.E., Prior Lake, Minnesota 55372-1714 / Ph. (612) 447-4230 / Fax (612) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER analyses of the corridor; achieve consensus about findings of fact from these analyses; achieve consensus about the deficiencies identified from the findings of fact; given the deficiencies, achieve consensus about the goals and objectives of the study; develop and test solutions to the deficiencies; and achieve consensus on solutions to be recommended in the final report. The goal stated in the study is to "Improve the operation of CH 42 as a regional highway in balance with existing and planned developments". CURRENT CIRCUMSTANCES Tr~~onsultant has finished a draft final report and submitted it fo'th~ counties. The counties have requested commeRts from each of the cities on the draft final report. The report includes a number of recommendations which. are included in Chapter 8, Recommended Corridor Implementation Plan (summarized in the Executive Summary). The recommendations address the key land usearld transportation deficiencies that were docum~nted during the study process. The key elements of the Recommended Plan are summarized below: \IItI. ;.".:....;~,U.'c:!o~. ~ -'!I!ft..;,'[.,.,- -'..J.:.; ~'^ , .i;~M;;j,! Cities should amend their comprehensive plans to provide the policy framework for access management, reductions in travel demand and to establish supporting roadway connections. The Counties should develop a model land use and access management ordinance to be implemented by the Cities for access management and reductions in travel demand. Dakota and Scott Counties should continue to cooperate and a corridor committee should be formed that has advisory status with the two County Boards. The establishment of Critical Principal Arterial Corridor legislation should be initiated which would establish a Corridor Commission with the power to coordinate the development of critical corridors, plan for improvements, and generate funding from within the corridor. CSAH42,DOC - A South Metro Corridor Coalition should be established. Formal variance procedures for access management should be established. ,",",-,!I."f:YNCTIONAL CLASSIFICATION The present Non-Freeway Principal Arterial functional classification of CH 42 should be maintained. Planning efforts should be initiated for developing an alignment and preserving the right-of-way for a new Principal Arterial roadway approximately 4 to 6 miles south of CH 42. (See Figure 8-1 in Executive Summary). Consideration should be given to designating all of the Supporting Roadways as A-Minor Arterials. III. ACCESS SPACING The Counties and Cities should adopt consistent access spacing guidelines for the entire corridor that have the following major provisions: 1. A target of one-half mile average spacing between full access signalized intersections. 2. Partial access (left-in and/or right-in/out) at intermediate locations. 3. No private driveway access to CH 42. 4. A hierarchy of access (driveways connecting to local streets and collectors, collectors to minor arterials and minor arterials to principal arterials. 5. A formalized variance process. 6. A joint powers variance review committee. The Counties should also adopt a prioritized plan for revising existing access points, consistent with the recommended guidelines, that is coordinated with the development/redevelopment of individual parcels and with the implementation of alternative access to the local/supporting street system. IV. RAILROAD CROSSINGS The Counties should adopt a policy requiring that all railroad crossings be grade separated. CSAH42.DOC ~. v. . TRANSIT ~,.,."",~,. The Counties and Cities should consult with the transit authorities on all major infrastructure improvements prior to plan completion. Early in the project development process, any needed transit improvements (bus pullouts, corner radii improvements, shoulder strengthening, etc.) should be identified. VI. PEDESTRIANS/BICYCLES The Counties and Cities should adopt a policy to promote pedestrian/bicycle usage in the CH 42 corridor by providing a continuous system of trails parallel to the roadway and a series of strategically placed grade separated crossings of the corridor. VII.ROADWAY IMPROVEMENTS - An enhanced system of supporting roadways should be provided in order to improve mobility in the CH 42 corridor. (See Figure 8-2 in the Executive Summary) - An enhanced system of local streets should be provided in order to reduce the need for direct driveway access to CH 42. Existing commercial, institutional, and residential driveways should be realigned to connect with the enhanced local street system as opportunities arise. Full access signalized intersections should be provided at an average spacing of approximately one-half mile. (It should be noted that the new traffic signals should be installed only after a detailed traffic engineering analysis suggests that the installation would be consistent with the guidelines in the Minnesota Manual on Uniform Control Devices.) Present intermediate full access intersections (Figure 6- 5) should be converted to partial access intersections based on one-quarter mile spacing for the three-quarter access design (Figure 6-6) and one-eighth mile spacing for the right-in/out design (Figure 6-8). - - A minimum of two lanes should be provided on all minor street approaches to signalized intersections. CSAH42.DOC - Auxiliary lanes should be provided at signalized intersections, where feasible, including right-turn lanes and single or dual left-turn lanes. Revised traffic signal operations should be considered, including the extension of coordinated systems, the elimination of split phasing, the addition of right-turn overlaps and the addition of exclusive/permitted phases where feasible. - The existing six-lane segments of CH 42 should be extended west through the intersection at Burnsville Parkway and to the east through the CR 11 intersection in order to accommodate future traffic volumes. - The existing four-lane segment of CH 42 between CH 23 (Cedar Ave.) and CH 31 (Pilot Knob Road) should be widened to six-lanes in order to accommodate future traffic volumes. Consideration should be given to revIsing the existing interchange at 1-35E and providing new grade separations at Aldrich Avenue, CH 23, and at the railroad tracks east of TH 3. Tnestudy is intended to provide an overall blueprint to guide future planning for roadway improvements in the CH 42 Corridor. Specific projects mayor may not be undertaken. Projects that are proposed will be evaluated based on their ability to meet the identified mobility, safety, and access goals identified in the study. ISSUES The functional classification of CH 42 as a Principal Arterial will have an impact on development along CH 42 in Prior Lake. One of the guidelines for a Principal Arterial is that the roadway should maintain at least 40 mph average speed during peak traffic periods. A satisfactory guideline to both the Metropolitan Council and MnDOT is that a speed objective should be to maintain and average speed of 40 mph along significant segments of the CH 42 corridor. It is expected that some portions of the corridor, where development is currently more intense, will operate at speeds less than 40 mph. Therefore, in other areas of less CSAH42.DOC FINANCIAL IMPACT: ALTERNATIVES: RECOMMENDED MOTION: REVIEWED BY: CSAH42.DOC intense development they will expect speeds in excess of 40 mph to achieve the 40 mph average. For instance, while the study recommends that the target speed between TH 13 and CH 21 be 40 mph it also recommends that west of CH 21 the target speed be 50 mph. In order to achieve the speed guideline for a Non-Freeway Principal Arterial it will be critical to control access to CH 42. It is anticipated that the County will adopt the recommended access spacing outlined in the study. The City will need to address the land use within the corridor in the context of the study recommendations. CONCLUSION The Council should decide if the recommendations from the draft final study are acceptable or not. Based on the discussion and decision at the Council meeting staff will prepare a response to the Counties outlining the City's position with respect to the draft final report. In any case, the comments made by Prior Lake should be subject to tne review and proposed revision of the Comprehensive Plan presently underway. The recommendations in the study if adopted by Scott County will influence the development of property in the CH 42 corridor within Prior Lake. This influence could affect future revenues to the City from property taxes. There is no way at this time to quantify this influence. The Council should discuss the recommendations in the draft final report and decide if they are acceptable or not and provide staff direction on formulating a response to Scott and Dakota Counties. A motion and second to accept the report and direct staff to forward the appropriate comments, based on Council discussion, to Scott and akota Counties. 1.0 EXECUTIVE SUMMARY Introduction (Chapter 2.0) County Highway (CH) 42, in Dakota and Scott Counties, is basically a multi-lane urban arterial roadway that is an integral component of the Regional road system. CH 42 serves a variety of functions, including: · it is the only continuous east-west roadway serving travel across central Dakota and northern Scott Counties · it provides direct connections to all of the major north-south freeways in the area · it provides access to a number of major regional commercial nodes and to a variety of retail land uses CH 42 is functionally classified as a non-freeway principal arterial roadway. And given this classification, it is clear that the primary function of the roadway is to accommodate the movement of through traffic (traffic that is using the roadway to get to a destination somewhere outside of the corridor). However, the intensity of the adjacent commercial development has created a demand for land access and controlled intersections to facilitate ingress and egress. This level of commercial development has generated large traffic volumes that have resulted in concerns regarding traffic operations characteristics (average travel speed and intersection delay) and the frequency of access has resulted in concerns relative to motorist safety. The conflict between the competing functions of CH 42 has created a dilemma for the road authorities responsible for operations and safety along the roadway and the local units of government who are responsible for regulating development. There is often pressure to provide high levels of accessibility to the roadway in order to support area business development. However, there is a wealth of research that indicates high levels of accessibility are directly related to inefficient traffic operations and increased crash rates. Therefore, the purpose of this study is to take a comprehensive look at both traffic and land development characteristics in the corridor and actively involve area residents and . representatives of the business community to better understand the key issues facing the corridor. Then, after reaching a general agreement with the study participants relative to the deficiencies in the corridor, develop an over!lll plan for the corridor that balances the 'need for mobility and safety with the need to maintain a reasonable level of accessibility to support area businesses and residents. It should be noted that this document is intended to provide an overall blueprint to guide future planning for roadway improvements in the CH 42 Corridor.' As individual projects are considered in the future for implementation by state, county or local jurisdictions, the results of this study will likely be supplemented with additional data and analysis to support detailed project planning and design as needed. During project development, new alternatives may be identified. However, all options being considered will be evaluated based on their ability to meet the identified mobility, safety and access goals. As specific projects move through the development process, opportunities will be provided for public and local agency review. COllnry Road 42 Corridor Study Final Report J-J Execwive Summary September JO, J998 The sections that folfdw document the extensive public involvement process, the results of the analyses of both traffic and land use issues, the approach to systematically developing agreement regarding corridor deficiencies and potential solutions and finally the recommended blueprint for the Corridor. Public Participation (Chapter 3.0) The public participation program for the CH 42 Corridor Study involved all of the key agency and public stakeholders in the study area. The program included both a Technical and an Advisory Committee, Public Information Open Houses, newsletters, public outreach, a web page and many opportunities for public input. As the Study progressed, the scope of work was expanded to include both additional technical analysis and an expanded Public Participation program. This resulted in not only more Technical and Advisory Committee meetings (for a total of 17 and 12, respectively) but also an iterative process where the results of each analysis was reviewed by the Committees prior to moving on to the next phase of the Study. Participants on the Technical Committee included engineering and planning professionals from Dakota and Scott Counties; the Cities in the Study Area; the Metropolitan Council; Mn/DOT and the Minnesota Valley Transit Authority. Participants on the Advisory Committee included residents and representatives of the business community in Dakota and Scott Counties and the Cities in the Study Area. The role of these Committees was to provide input into the planning pTocess and to provide two-way communication between the Project Team and the Committee participants various constituencies. The participants on the Committees and their role in the Study process are illustrated in the following figures. Additional opportunities for public participation included three Public Information Open Houses, presentations to various business and civic groups and the distribution of five ~ewsletters. Preliminary Technical Analysis (Chapter 4.0) The preliminary technical analysis consisted of identifying and then documenting the key results of investigations relative to six issue areas in a series of Technical Memorandums. The six issue areas and a summary of the key conclusions are documented below: Technical Memorandum #1 - Literature Search · Access management is a legitimate public safety issue and access management strategies can reduce crash frequencies and increase the operational efficiency of urban arterial roadways.

Technical Memorandum #2- Land Use Analysis · All of the Cities in the Study Area rely on the Counties for addressing access management issues on County Highways. · . Access spacing guidelines must be flexible enough, particularly in commercial areas, to maintain a reasonable level of accessibility in order to support area businesses. · The Metropolitan Council and Mn/DOT suggested that the mobility objective should be based on maintaining an average speed of 40 miles per hour (MPH) across the corridor. This infers that some segments of the Corridor will be expected to operate at speeds greater than 40 MPH (basically the more rural areas at the ends of the Corridor) and the more densely developed areas (primarily in Apple Valley and Burnsville) will be expected to operate at speeds in the range of 20 to 30 MPH. · Mn/DOT and the Metropolitan Council acknowledged that flexibility in the application of access spacing guidelines would likely be required in densely developed areas. However, they also encouraged the adoption of an overall blueprint for the corridor in order to guide future planning of roadway improvements, that could be implemented in conjunction with development or redevelopment projects. Technical Memorandum #3 - Functional Classification · CH 42 is fun.ctionally classified as a non-freeway principal arterial, roadway and is on the National Highway System. If CH 42 were to be reclassified as a minor arterial, a potential source of federal highway funds would be lost. · A principal arterial roadway in the CH 42 Corridor is consistent with regional policies and guidelines. Technical Memorandum #4 - Vehicle Trace Survey · The average trip length along CH 42 is greater than three miles and most trips along the '-' corridor are considered through traffic (traffic that is using the roadway to get to a destiriation somewhere outside of the corridor). Technical Memorandum #5 - Traffic Forecasting · Current local land use plans suggest that substantial growth is expected to occur in the travel shed of the CH 42 corridor and, as a result, traffic demand is expected to increase by a minimum of 20% to more than 100%. COllnry Road 42 Corridor StlIdy Filial Report 1-3 Executive Summary September 10, 1998 Technical Memorandum #6 - Traffic Engineering Analysis "':> . The CH 42 corridor experiences a moderate level of peak period congestion under existing conditions, and the projected growth in traffic demand will result in more severe and extensive congestion under the Year 2020 No-Build Scenario. Systematic Development of Solutions (Chapter 5.0) During the initial information gathering, public participation and analytical steps in the CH 42 Corridor Study, it became apparent that there was no consensus as to the magnitude of the problems facing the corridor, and therefore no agreement as to how to address corridor issues and develop a corridor blueprint. As a result, the Project Team created and initiated an interactive and iterative process to systematically develop a general description of potential solutions. The process involved documenting the following issues: . Findings of Fact . Goals and Objectives . Identification and Prioritization of Deficiencies . General Description of Potential Solutions The results of each step were submitted to the Committees for review and discussion and then revised as necessary prior to moving on the next step in the process. This process generated general agreement with the results of each effort on the part of both the Technical and Advisory Committees. The key Findings of Fact were documented in the six Technical Memorandums. The basic Goal involves.improving traffic operations of CH 42 as a regional roadway in balance with existing and planned development. Objectives were identified dealing ,with safety, economic developmentlland use, supporting roadways, access and mobility. The general description of potential solutions included the following basic items: · Safety Provide additional 'turning lanes. Implement turn restrictions/median modifications. · Economic Development/Land Use Identify more compatible land. use patterns. Develop model land use and zoning regulations. . Supporting Roadways Extend existing roadways that are parallel to CH 42 in order to provide new connections among neighborhoods, commercial areas and communities. Identify a search area for a new east-west principal arterial roadway south of CH 42. Provide new connections and directional signage in order to divert through and local traffic to available alternative routes. County Road 42 Corridor Swdy Filial Report 1-4 Executive Summary September 10. 1998 . Access Develop land use-based guidelines that include a hierarchy of access, i.e.: private driveways connect to local streets and collectors, collectors connect to minor arterials, minor arterials connect to principal arterials. Develop a formal access variance process consistent in both Dakota and Scott Counties. . Mobility Increase capacity by providing additional auxiliary turning lanes and/or through lanes Increase capacity by improving the efficiency of the existing roadway through access modification/limitations and improved signal coordination. Detailed Traffic Operations Analysis (Chapter 6.0) The detailed technical analysis of future (Year 2020) traffic operations considered eight different scenarios that included various combinations of signal phasing, roadway geometry, signal removal and supporting roadway improvements. Each scenario was modeled using traffic simulation software. Development of the recommended mitigation scenario was an iterative process, with each scenario building on the scenario that preceded it. The analytical process is illustrated in Figure 6-1, and shows how the analysis was structured and how each scenario relates to the others. The basic roadway scenarios can be described as follows: . No-Build Scenario - Includes traffic signal build out and committed geometry improvements. . Suppor.ting Roadway Scenario - Includes adjusted traffic forecasts dueto diversions associated with implementing improvements to supporting roadways. . Scenario'} - Includes Low Co'st Improvements generally co~sisting of traffic signal modifications and the addition of auxiliary lanes on the minor street approaches to signalized intersection. . Scenario 2 - Includes Moderaie Cost Improvements generally consisting of CH 42 geometric improvements or the removal of traffic signals to achieve optimum traffic signal efficiency. .. Scenario 3 - Includes High Cost Improvements generally consisting of-grade s:eparated ' interchanges at the higher volume intersections. · Scenario 4 - Includes the Supporting Roadways, the LowCostlmprovements and the most feasible combination of Moderate and High Cost Improvements. . Recommended Scenario - Includes all Recommended Improvements. The key measures of effectiveness for traffic operations are either intersection delay or arterial speed.

The letter A represents_conditions with no congestion, C represents average levels of congestion and F represents severe congestion. For the purposes of this Study the LOS DIE boundary represents the on set of unacceptable congestion. The results of the operations analyses are documented in Tables 6-4 and 6-5 and summarized below: · There is little recurring congestion today and all of the key intersections and roadway segments meet the delay, speed and LOS objectives for the Corridor. · The 2020 No-Build Scenario results in significant congestion along major segments of the Corridor. · The addition of the Supporting Roadway System would improve conditions slightly, but not to the point where delay, speed and LOS objectives would be achieved. · The addition of Low Cost Improvements would improve conditions slightly, but not to the point where delay, speed and LOS objectives would be achieved. · The Moderate Cost geometric improvements would improve conditions to the point where all LOS objectives are achieved, with one exception, the intersection of CH 42 and CH 23 (Cedar Avenue). · The Moderate Cost signal removals provide about the same LOS as the Low Cost scenario, and therefore do not achieve the LOS objective. · The H~gh Cost Improvements would achieve the LOS objective at all of the locations where they were implemented. · The Recommended Mitigation Scenario meets all of the delay, speed and LOS objectives. Environmental Overview (Chapter 7.0) A preliminary review was conducted of cultural, natural and comrTiuility resources in the CH 42 Corridor. The purpose of this review was to document know resources in a'one-haIf mile wide area centered on ci-I 42 and to make a preliminary assessment ofthe:potential for enviPOnmental impacts associated with the implementation of any of the recommended roadway improvements. The results of this environmental overview are documented below: · Cultural Resources - A review of the Minnesota Standing Structure and Archaeological Site database found a total of 51 properties in the CH 42 Corridor. However, it was determined that the various roadway improvements would have a very low probability of impacting any of these properties. · Natural Resources - A variety of natural resource databases were reviewed in order to document the presence of floodplains, farmlands, wetlands and any other unique COllnty Road 42 Corridor Study Final Report 1-6 Executive Summary September 10, 1998 environmental features. The review found a number of areas where the recommended roadway improvements would likely impact floodplains, prime farmlands and/or wetlands. These areas will require further and more detailed study, in the future, during the project development phase of any of the individual roadway improvements. However, at this time it appears that any potential impact could be adequately mitigated and therefore would not prevent the implementation of any of the roadway improvements. . Community Resources - A GIS database was reviewed and 40 community resources (public buildings, parks, churches, etc.) were identified. It was determined that most of these facilities are not located adjacent to CH 42 and therefore would not likely be directly affected by any of the roadway improvements. However, a number of these facilities could be impacted by changes in access and as a result, will require further and more detailed study, in the future, during the project development phase of any of the individual roadway improvements. . Air Quality - Air quality is primarily a function of the level of traffic operations in a roadway corridor. Therefore, if traffic volumes increase as forecast and no improvements are implemented, congestion could reach sever levels which would result in the degradation of air quality and concentrations of carbon monoxide approaching air quality standards. Implementation of the recommended roadway improvements would resolve any potential air quality concerns. · Land Use - The potential impacts on both existing and future land uses associated with the various roadway improvement scenarios was assessed. The assessment was based on information gained through a series of meetings with the planning staffs in each of the cities in the corridor, interaction with members of the Advisory Committee, a review of the case law regarding the legal definition of compensable right of access, recent research studies and a thorough in field review of the corridor. The key conclusions of the assessment are as follows: Doing nothing is not an acceptable alternative and would have a significant adverse affect on the overall business vitality of the corridor. The low cost roadway improvements (basically signal modifications and cross street auxiliary lanes) would have minimal impact on land uses., The moderate cost roadway improvements that revise access to ,and from CH 42 (the removal of private driveways and the conversion of full access to partial access intersections) have the potential to favorably affect mobility but could have a greater adverse impact on some specific businesses that are not destination oriented. The changes in access should not affect the overall business vitality of the CH 42 corridor and co,-!ld be mitigated if they are timed to coincide with development and/or redevelopment projects and if new connections are provided (via new frontage roads, backage roads or easements across existing parking areas) to the remaining full access intersections. County Road 42 Corridor Study Filial Report ]-7 Executive Summary September ]0, ]998 Recommended Corridor Implementation Plan (Chapter 8.0) -, The blueprint that identifies a plan for the future of CH 42 addresses the key land use and transportation deficiencies that were documented during the study process. The land use recommendations primarily deal with the development process and the interaction with the supporting transportation infrastructure. The transportation recommendations are multi-modal in nature but focus on functional classification, access spacing and a variety of roadway geometry and traffic signal system improvements. The key elements of the Recommended Plan are summarized below: · Land Use Cities should amend their comprehensive plans to provide the policy framework for access management, reductions in travel demand and to establish supporting roadway connections. The Counties should develop a model land use and access management ordinance to be implemented by the Cities for access management and reductions in travel demand. Dakota and Scott Counties should continue to cooperate and a corridor committee should be formed that has advisory status with the two County Boards. The establishment of Critical Principal Arterial Corridof'legislation should be initiated which would establish a Corridor Commission with the power to coordinate the development of critical corridors, plan for improvements anti generate funding from within the corridor. A South Metro Corridor Coalition should be established. Formal variance procedures for access management should be established. · Functional Classification '" The present Non-Freeway Principal Arterial functional classification of CH 42shouldbe maintained.. .. Planning efforts should be initiated for developing an alignm-ent and preserving the right- of-way for a new Principal Arterial roadway approximately 4 to 6 miles south of CH 42. (See Figure 8-1.) Consideration should be given to designating all of the Supporting Roadways as A-Minor Arterials. COl/llty Road 42 Corridor Study Fina!

Early in the project development process, any needed transit improvements (bus pullouts, comer radii improveme'nts, shoulder strengthening, etc.) should be identified. · Pedestrians/BicycIes The Counties and Cities should adopt a policy to promote pedestrian/bicycle usage in the CH 42 corridorby providing a continuous system of trails parallel tothe roadway and a series of strategically placed grade separated crossings of-the corridor. · RoadwayJrnprovements An enhanced system of supporting roadways should be provided in order to im'prove mobility in the CH 42 corridor. (See Figure 8-2.) . An enhanced system of local streets should be provided in order to reduce the need for direct driveway access to CH 42. Existing commercial, institutional and residential driveways should be realigned to connect with the enhanced local street system as opportunities arise.

Full access signalized intersections should be provided at an average spacing of approximately one-half mile. (It should be noted that new traffic signals should be installed only after a detailed traffic engineering analysis suggests that the installation would be consistent with the guidelines in the Minnesota Manual on Uniform Traffic Control Devices.) Present intermediate full access intersections (Figure 6-5) should be converted to partial access intersections based on one-quarter mile spacing for the three-quarter access design (Figure 6-6) and one-eight mile spacing for the right in/out design (figure 6-8). (It should be noted that if all of the recommended access revisions are implemented, the total number of accesses in the corridor would be reduced by less than 10 percent, from 406 to 370, and that the average access density would decrease by only one access per mile. See Table 8-3.) A minimum of two lanes should be provided on all minor street approaches to signalized intersections. Auxiliary lanes should be provided at signalized intersections, where feasible, including right-turn lanes and single or dual left-turn lanes. Revised traffic signal operations should be considered, including the extension of coordinated systems, the elimination of split phasing, the addition of right-turn overlaps and the addition of exclusive/permitted phases where feasible. The existing six-lane segments of CH 42 should be extended to the west through the intersection at Burnsville Parkway and to the east through the CR II intersection in order to accommodate future traffic volumes. The existing four-lane segment of CH 42 between CH 23 (Cedar Avenue) and CH 31 (Pilot Knob Road) should be widened to six-lanes in order to accommodate future traffic volumes. Consideration should be given to revising the existing interchange arI-35E and providing new grade separations at Aldrich A venue, CH 23 and at the railroad tracks east of TH 3.
