86th Street Bridge and 82nd Street Bridge Construction

 

Background

During the 2017 construction season MnDOT will be replacing the W. 86th Street Bridge over Highway I-35W. Replacement of the bridge became critical after an accident on I-35W caused structural damage to the bridge and the underlying utilities in February of 2016. Past accidents, due to vertical clearance issues, contributed to the decision to replace the bridge and increase the vertical clearance. The project will be managed by MnDOT and will be coordinated with City staff and any projects adjacent to the area. The project is expected to last from late June to October of 2017.

Additional rehabilitation work has been ordered for the W. 82nd Street Bridge over I-35W to repair damage sustained to a bridge girder earlier this year. This rehabilitation work will be coordinated with the W. 86th Street Bridge Project.

Additional Information

Traffic Impacts

  • The bridge will remain closed for the duration of the project.
  • Traffic on W. 82nd Street across the bridge will continue to be limited to one lane in each direction until further notice.
  • Detours guiding motorist to American Boulevard for local destinations and I-494 for highway access will be used to limit congestion on W. 82nd Street
