Highway 56 Project

This spring through fall, 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.

Road construction is scheduled to begin in early May. Construction is anticipated to be completed by fall 2024. The Minnesota Department of Transportation (MnDOT)also plans to conduct additional landscaping work (tentatively in 2025), which would include adding new trees to boulevards.


As part of the project, MnDOT will:

  • Reconfigure the Mower County Road 12, Highway 56 and East Main Street intersection to improve safety by reducing vehicle speeds while maintaining efficient traffic flow.
  • Construct a cul-de-sac west of Mower County Road 12.
  • Create a buffer zone between traffic and parking from Mather to Everett streets for biking.
  • Improve school crosswalk safety by constructing a bump-out in front of the school and creating a wider school parking zone.
  • Replace aging storm water, sanitary sewer and water main utilities underneath Main Street
  • Extend the water main past Ada Street.
  • Replace and install new curb and gutters.
  • Replace and install new sidewalks.
  • Install new landscaping, such as adding trees to boulevards (likely in 2025)

Construction Schedule

The project will be completed in two phases:

  • Phase 1: When construction begins on May 6, crews will initially work on both ends of Main Street. The construction zones will be from County Road 56 to South Mather Street and from Everett Street to east of Ada Street.
  • Phase 2: While construction on the west side of Main Street (East County Road to Mather Street) is expected to last through the middle of August, construction on the east side of Main Street (Everett Street to Ada Street) is expected to wrap up in early July. Once eastside and westside construction are complete, crews will begin construction on the downtown stretch from Mather Street to Everett Street.

Affected businesses and residents who have questions about access to their properties can call Trevor Minnich (507-272-3142) or Tim Heins (507-208-3840) throughout the project to share any concerns, ask questions and receive guidance.
