About this project

Update

Motorists on Hwy 43/Mankato Ave. will encounter lane closures and brief traffic stoppages with flaggers through the end of July as the contractor completes final work on the roundabout project in Winona.

The contractor on the project, which was substantially completed in 2022, has been finishing final work such as landscaping, paving, signs, striping and concrete repairs this year. Lane closures and brief stops of traffic with flaggers will be required to complete the remainder of the work.

Reasons for reconstruction

MnDOT reconstructed this stretch of Hwy 43 to improve safety and decrease congestion. Thousands of residents, commuters and business owners rely on the 3/4 mile stretch of Hwy 43/Mankato Ave. between Sugar Loaf View and Bellview St. in Winona each day.

This stretch of road needed to be improved. There have been 120 crashes at the Hwy 61 and Hwy 43 intersection over the past 10 years which is the second-highest crash rate for any stretch in southeast Minnesota. People traveling on this road also experienced longer-than-average delays and traffic back-ups during rush hour. Meanwhile, pedestrians and bicyclists had a difficult time crossing the road.

Stages of construction

  • Created one lane of traffic in each direction on Hwy 61. There was also work on the north side of Sarnia St.
  • Reconstructed a significant portion of the Hwy 61/Hwy 43 intersection as well as the eastbound lanes on Hwy 61, East Lake Blvd., the west side of Mankato Ave. from Sugar Loaf View to Frontenac Dr. and the east side of Mankato Ave. from Frontenac Dr. to Belleview St.
  • Work occurred adjacent to the main roadways and a portion of the box culvert located just south of Sarnia St. at Gilmore Creek was replaced
  • Reconstructed the east side of Mankato Ave. from Sugar Loaf View to Frontenac Dr., the west side of Mankato Ave. from Frontenac Dr. to Belleview St. and the south side of Sarnia St.
  • Minor work occurred along the highways including median treatments and roundabout center island landscaping.
