Hwy 43 Bridge


Winona Bridge opens to traffic

On Saturday, Aug. 27, 2016 the community held a celebratory dedication event and the Winona Bridge No. 85851 opened to traffic. The intersection of 4th Street and Winona Street is now open and all traffic can cross the new bridge, while Bridge No. 5900 is closed for rehabilitation.


The city of Winona, in partnership with the Minnesota Department of Transportation, will mark the re-opening of the historic Highway 43 Winona Bridge on July 1.

MnDOT has been working with the city of Winona to plan a noon ceremony with speeches and a ribbon cutting to mark the return of traffic on the bridge, which crosses the Mississippi River. The bridge has been closed since 2016 for rehabilitation work on the structure. Traffic has been using the new bridge upriver from Winona during this phase of the project.

The event will be at the foot of the historic bridge. The public is invited.

“This is a historic day for our city as the Winona Bridge project comes to a conclusion,” said Winona Mayor Mark Peterson. “We have added a new bridge in 2016 and now the historic bridge has been rehabilitated to ensure we can rely on it into the future and maintain one of our city’s signature symbols.”

Meanwhile, Ames Construction, the prime contractor, is working to keep the project on track to open to traffic later in the day on July 1. After traffic is opened, workers will be doing site work around the bridge this summer to wrap up the project.

Bike trail closures

The bicycle trail on the levee under the Winona bridge is closed during construction until late 2019. Bicyclists should detour from Johnson Street to Second Street to Riverview Drive.

The section of the bike trail from Riverview Drive to the bridge, which will be used as construction access, will be rebuilt as part of the project and re-opened following construction.

MnDOT is moving ahead with a two-bridge solution that rehabilitates the existing bridge and builds a new permanent bridge immediately upstream of the existing bridge. We've gotten some questions about why the existing Cass Street Bridges in La Crosse include a tied arch structure next to a through truss as well as why the plans for the new Red Wing Bridge include a tied arch bridge alternate, while the new Winona Bridge is planned to be built using a concrete box girder design along with rehabilitation of the existing bridge. The answer is: due to several factors, a tied arch design was considered as an option for the new Winona Bridge project but the concept did not ultimately become the recommended new bridge type.

Key issues


  • July 2014: Start of construction. Contractor starts building temporary access facilities on both sides of the river.

  • January 1, 2015: MnDOT possession of Right-of-Way. Start of demolition of buildings that are being acquired.
  • March 2015: Proceed with roadway work on both sides of the river, including in Winona, and with the remainder of the work to construct the new bridge.
