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:
May 15, 2206:
On Tuesday, May 19, 2026, the eastbound on-ramp at exit 332 (Mitchell) on Interstate 90 will be closed. The closure is for repair of the railroad bridge located at the end of the ramp. During the scheduled closure, ramp traffic will follow a signed detour west to exit 330 and back onto I-90 using the exit 330 eastbound on-ramp.
The closure of the eastbound on-ramp at exit 332 is scheduled to reopen on Tuesday, Aug. 4, 2026.

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.
