What is the Highway 42 & County Road 73/Akron Avenue Intersection and Median Modification Project?
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 east of Akron to promote safety by allowing movements from Highway 42 while restricting left turns from driveways and Dakota County Technical College (DCTC)
-
Add turn lanes to improve mobility at the intersection
-
-
Reasons for the Project
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.
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.

Intersection Traffic Control
ALL-WAY STOPS
TRAFFIC SIGNALS
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
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
THE DECISION TO INSTALL SIGNALS IS BASED ON:
Traffic volumes
Crash history
Vehicle delays
Anticipated crash rate
-
-
Why a Traffic Signal
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
REASONS FOR MANAGING ACCESS:
-
Designates where and how vehicles enter and exit
-
Helps protect public investment in roadways and improve public safety
-
Preserves mobility and reduces delay
-
Improves safety by reducing movements at intersections
-
-
Next Steps
Team will summarize input from the virtual meeting and post on the website
Design and right of way will continue through the summer
A meeting to share the final design and answer questions about construction will be scheduled in fall 2020
