    What is the Highway 42 & County Road 73/Akron Avenue Intersection and Median Modification Project?

    Proposed Project Improvements Project Overview Map

    CLICK HERE TO VIEW THE FULL PROJECT LAYOUT

    Dakota County, in collaboration with the  City of Rosemount, is planning to make the following improvements at the intersection of Highway 42 and County Road 73/Akron Avenue:

    install a traffic signal with overhead lighting

  • install a raised median

    add turn lanes to improve mobility at the intersection

The County will also install a raised median on Highway 42 east of County Road 73/Akron Avenue. This change will promote safety by allowing left turns from Highway 42 and all right turn moves while restricting left turns from driveways, including the Dakota County Technical College (DCTC) driveways, onto County Highway 42.

  • Reasons for the Project

    Checkmark Icon

    TRAFFIC SAFETY AND OPERATIONAL ISSUES

    Motorists on Highway 42 are having increased difficulty making left turns at the DCTC entrances and at the County Road 73/Akron Avenue intersection.

    Checkmark Icon

    INCREASED TRAFFIC VOLUMES AS A RESULT OF FUTURE DEVELOPMENT

    Existing delays at the Highway 42/County Road 73/Akron Avenue intersection are unacceptably high and are anticipated to increase with the expected growth in traffic along Highway 42 and County Road 73/Akron Avenue.

    ROUNDABOUTS

    USED FOR

    Moderate traffic volumes

  • Balanced traffic

    Speed limits of 40 mph or less

    Consistently high volume of traffic

    Collector or arterial corridor intersections

    Moderate to high traffic volumes

    Improving traffic flow

    Line

    DRAWBACKS

    Inefficient and cause delay

    Multiple lanes can cause crash risk

    Increased crash risk when disregarded

    Constant stopping/acceleration is noisy

    Introduces additional decision making

    Increased crash risk when disregarded

    Increased risk of fatal or serious injury crashes

    Creates delay, particularly for higher volume movements

    May have higher construction cost and right-of-way needs

    Potential for more property damage crashes

    Not suitable for six-lane or principal arterial highways

  • Traffic Signals

    TRAFFIC SIGNALS ARE EFFECTIVE BECAUSE THEY:

    Manage high volumes of traffic conflicts

  • Provide crossing opportunities

    Can improve intersection efficiency

    NEW SIGNALS ARE ADDED WITH CAUTION BECAUSE:

    Crashes often increase, especially rear-end crashes

    Crashes at signals are typically more severe

    Can increase delay and driver decision-making along Highway 42

    Flagstaff Ave Traffic Signal Intersection
    Generic Do Not Cross Traffic Signal

    THE DECISION TO INSTALL SIGNALS IS BASED ON:

    Traffic volumes

    Crash history

    Vehicle delays

    Anticipated crash rate

  • Why a Traffic Signal

    Proposed Project Improvements Project Overview Map

    The number of lanes and vehicle volumes are too high at this intersection for stop signs to function safely and efficiently.

    A roundabout was not selected based on the function of Highway 42, which is a principal arterial roadway designed for higher mobility.

  • Access Management

    DEFINITION:

    The systematic control of the location, spacing, design, and operation of driveways, median openings, interchanges, and street connections to a roadway

  • Designates where and how vehicles enter and exit

    Helps protect public investment in roadways and improve public safety

    Preserves mobility

    Reduces delay

    Minimizes crash problems
