About the Project

Mankato Avenue is an important and heavily-utilized corridor in the city of Winona – serving as the single artery on the east side of Lake Winona and doubles as Highway 43 (TH 43), which is the only route to cross the Mississippi River for nearly 30 miles in either direction. Its intersection with Highway 61, just south of Lake Winona, serves as a critical access point between Winona, Interstate 90 and the greater region. Under the Mississippi River bluffs and Sugar Loaf rock pinnacle, the Mankato Avenue corridor serves as an entryway to Winona from the south.

MnDOT and the City of Winona have determined that approximately one-half mile of TH 43 (Mankato Avenue) in Winona requires reconstruction. A project that has been
discussed in one form or another for decades, this project calls for the reconstruction of TH 43 south of TH 61 to Sarnia Street.

The Mankato Avenue Reconstruction Project will take place for half mile between Sarnia Street and south of TH 61 in Winona. The map below illustrates the corridor and the land use conditions that currently exist along the road. This project will also address key intersections along Mankato Ave: 

  • Sarnia Street

  • Frontenac Drive

  • Riverbend Road

  • Bruski Drive

  • US 61 / US 14

Project Schedule

The project started in early 2019 and concludes with construction in 2022, shown in the project schedule below. There are numerous opportunities to learn more and to provide input throughout the project including public open house meetings, listening sessions, bike and walk audits, online surveys and interactive mapping. You can also leave comments through the website here. The project team plans to complete the project in December 2022.
