A 1.2-mile stretch of Hwy 56 will be reconstructed in LeRoy to address deteriorating pavement conditions, improve drainage, enhance student crosswalk safety and make pedestrian improvements to meet current accessibility standards. At the same time, the City of LeRoy will replace aging city utilities underneath the road.
Construction for this project will take place in three stages in 2024. Learn more in the traffic impacts section below.
Construction is scheduled to begin April 29, 2024. It anticipated to be completed in October 2024. MnDOT also plans to conduct additional landscaping work (tentatively in 2025), which will include adding new trees to boulevards.
The following is the planned work:
Reconfigure Mower Co. Rd. 12, Hwy 56 and Main St. E. intersection to improve safety by reducing vehicle speeds while maintaining efficient traffic flow
Construct a cul-de-sac west of Mower Co. Rd. 12
Create a buffer zone between traffic and parking from Mather St. to Everett St. for biking
Improve school crosswalk safety by constructing a bump out at Mower Co. Rd. 14 and creating a wider school parking zone
Replace aging storm water, sanitary sewer and water main utilities underneath Hwy 56
Extend water main past Ada St.
Replace and install new curb and gutter
Replace and install new sidewalks
Landscaping, such as adding trees to boulevards (likely in 2025)
Below are project plans and detour routes. The timeframes are weather dependent. Construction will take place in three stages to better align with the city’s sewer reconstruction efforts.
People will be able to reach their destination within the construction zone. However, which direction they take may depend upon the day’s work.
