Bike path closed under Winona bridge

The bicycle path on the levee under the Winona bridge will be closed beginning the week of July 21 so the contractor can begin construction work to build a new bridge across the Mississippi River. Weather permitting, construction on the Winona Bridge project will begin that same week. The bike trail closure is expected to last until late 2019. Bicyclists should detour from Johnson Street to Second Street to Riverview Drive. View/print bike detour map (PDF). 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.

Weight restrictions

The Hwy 43 Winona bridge has a gross weight limit of 80,000 pounds until further notice.

The Winona Bridge carries an average of
11,300 vehicles per day

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


  • $150 million to $175 million (total planning-level cost estimate; cost range includes right-of-way, design and construction contract administration and reflects a number of unknowns and assumptions)
