MoDOT Proposes Major Traffic Changes Along Karsch Boulevard in Farmington
FARMINGTON, Mo. — The Missouri Department of Transportation (MoDOT) is evaluating several potential improvements along Karsch Boulevard in Farmington, including changes to traffic signals, intersections, turning lanes, pedestrian crossings, and access to businesses.
The Route 32 Corridor Study covers the stretch of Karsch Boulevard between U.S. Highway 67 and Route OO (Sainte Genevieve Road).
According to MoDOT, the goal is to improve traffic safety, reduce congestion, and address traffic conflicts along one of Farmington’s major commercial corridors.
Six Major Intersections Under Review
MoDOT has identified six intersections for possible improvements, with preliminary cost estimates ranging from $100,000 to $875,000 per intersection.
Route 32 and Maple Valley Drive — $650,000 to $750,000
Proposed improvements include modifying left-turn signals, adjusting the intersection layout, and extending the southbound right-turn lane.
One significant proposal would restrict access at Maple Valley Drive/Valley Creek Drive to right turns only when entering or exiting, eliminating certain left-turn movements.
Route 32 and Walton Drive — $775,000 to $875,000
MoDOT is considering modifications to left-turn signals and intersection geometry to improve visibility and traffic flow.
The proposal also includes a new right-in/right-out access point between Maple Valley Drive and Walton Drive.
Route 32 and Potosi Street — $750,000 to $850,000
Potential improvements include changes to left-turn signals, adjustments to the intersection layout, and new sidewalks and signalized pedestrian crossings.
MoDOT is also considering additional signage and curbing at the Walgreens entrance to reinforce its entrance-only designation.
Route 32 and Washington Street — $400,000 to $500,000
Proposed changes include improvements to left-turn signals, adjustments to the northbound approach, updated pavement markings, and modifications to intersection islands.
The study also identifies a sidewalk ramp replacement and additional guardrail near a drainage structure.
Route 32 and Krei Boulevard — $100,000 to $150,000
MoDOT is considering changing the angle of the southbound approach to improve drivers’ visibility when entering Route 32.
A raised traffic island and designated right-turn lane are also being evaluated.
Route 32 and Route OO/Sainte Genevieve Road — $450,000 to $550,000
The proposed improvements focus on modifying right-turn lanes and improving visibility for drivers traveling through the intersection.
Changes Could Affect Business Access
Beyond intersection improvements, MoDOT is also studying access management along Karsch Boulevard.
That could include reducing, consolidating, or modifying some driveways and access points along the roadway.
According to MoDOT, these changes are intended to reduce conflicts between vehicles entering and exiting businesses and those traveling along Route 32.
However, the proposals could also affect how customers reach certain commercial properties, depending on which changes are ultimately approved.
Proposed Improvements Could Total More Than $3 Million
Based on MoDOT’s preliminary estimates, the six intersection projects have a combined estimated cost of approximately $3.13 million to $3.68 million.
These figures represent potential improvements under consideration, not an approved construction budget.
No Construction Funding or Final Decisions Yet
MoDOT emphasizes that the corridor study remains in progress.
No final decisions have been made regarding intersection improvements, driveway restrictions, or other access changes.
The project also does not currently have construction funding.
The study will help MoDOT determine which improvements should advance into additional planning, engineering design, and public coordination.
Residents Can Review Proposed Changes
Farmington residents, business owners, and motorists can review the corridor study, intersection exhibits, and public meeting materials on MoDOT’s website.
