Overall, the City of Winona will remain open for business throughout the duration of this project and commuters, visitors and shoppers will have little to no travel impacts. This is mainly due to the addition of a second new bridge to the project scope, allowing the new bridge to be built offline first, while traffic is maintained on the existing structure. Once Hwy 43 traffic is switched to the new structure, the existing bridge will be rehabilitated and reconstructed.
Latsch Island Bridge Detour
Beginning Monday, April 18th, traffic coming from Wisconsin to Latsch Island cannot make the right turn directly onto Latsch Island. Instead, continue into Winona, then follow these directions (PDF) to continue back onto the bridge. This detour will be in place for about one month.
The Hwy 43 Mississippi River Crossing will stay open at all times throughout the project.
Peak hour traffic impacts on Hwy 43 across the river will be minimized.
3rd Street and 2nd Street will not be closed at the same time; 2nd Street closures will be limited to weeks in duration, while 3rd Street may have long term closures.
Pedestrians will be accommodated throughout the project, and pedestrian routing during Hwy 43 detours will be coordinated closely with city staff.
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.
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. View/print project overview map (PDF).
The Hwy 43 Winona bridge has a gross weight limit of 80,000 pounds until further notice.
Informational tours are being held on boat cruises so that viewers can safely and conveniently view the bridge progress. During each tour, MnDOT representatives will give a presentation and informally field questions and answers, while the tour provides fairly close-up viewing of the bridge progress.
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.
