Road and trail closures

MnDOT is undertaking a multi-year project to repair 10 bridges on TH 77 between 494 and the Minnesota River. These bridges include ramps to and from TH 77 to 494, numerous ramps around the Mall of America, and the Minnesota River Bridge. This project is phased to minimize conflicts with the upcoming MnDOT 494 Project 2 and MnDOT has also been coordinating with representatives of the Mall of America. Motorists can expect road, lane, ramp and bridge closures during construction. Work is schedule for summer 2026 through November 2028.
