Summary of work

I-494 Ramp Closures
The Winona Bridge carries an average of
11,300 vehicles per day

MnDOT has recommended 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.
