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.
