On April 8, the Minnesota Department of Transportation closed the Stillwater Lift Bridge. The bridge closure has meant additional traffic along Highway 35 (Second Street in Hudson and Sixth Street North in North Hudson). According to the city's website, the three traffic signals on Second Street "have been synchronized with longer times for vehicles traveling north/south on Second Street, to improve the flow of traffic." The bridge will not be reopened until the river level recedes to a "safe level," which typically means about 686.2 feet. 

On April 7, Hudson city workers closed a portion of First Street along , between Buckeye Street and Wisconsin Street. Businesses in the Riverfront Square building on Buckeye Street (,  and ) are not affected and remain open. Portions of Front Street have been under water for nearly three weeks.
