Interstate 90 Bridges in Mitchell
Project Summary:
The project includes replacing bridge approach slabs and joints to provide a smoother transition on and off the structure. Berm repairs and improvements to the approach pavement will also be completed to enhance ride quality and extend the life of the roadway.
A polymer chip seal will be applied to help protect the surface from moisture and wear. Guardrail upgrades will improve roadside safety, and an acceleration lane will be constructed to allow drivers to safely merge into traffic.
Project Updates:
March 20, 2026:
Work is scheduled to begin in late March 2026 at Interstate 90 Exit 332. The project includes reconstructing the approaches to the bridge over the railroad and adding acceleration and deceleration lanes at Exit 332.
During construction, I-90 traffic will be reduced to a single lane in each direction. Vehicles wider than 12 feet will be detoured around the project via U.S. Highway 34.
