Fargo-Moorhead Main Avenue Bridge over the Red River

Fargo, North Dakota & Moorhead, Minnesota

A combination of geometric, structural, and flooding issues led MnDOT and NDDOT to consider replacing the Main Avenue (US 10) Bridge over the Red River. The 825-foot bridge serves as a gateway to the cities of Moorhead and Fargo, and the development of the bridge replacement project was an effort involving both states and both cities.

After preparing the bridge concept development report, SRF prepared design documents for:

  • Replacing the TH 10 bridge
  • Reconstructing roadway approaches in each city to meet the new, higher bridge profile
  • Reconstructing 3rd Street in Moorhead as a riverfront parkway on a new alignment beneath the east end span of the bridge

Urban aesthetic treatments, an important part of the design, included gateway towers, ornamental railings, lighting, and historic information plaques. Bridgehead plazas create pedestrian connections to the riverfront, and a unique mid-span plaza provides spectacular views of the Red River corridor. The Main Avenue Bridge has been heralded as a new landmark for the Fargo-Moorhead area.
