Traffic to shift tomorrow on Missouri Route 8 bridge over Union Pacific Railroad

March 05, 2026

JEFFERSON CITY, Mo. – A long-awaited milestone in the rehabilitation of the Missouri Route 8 bridge over the Union Pacific Railroad in Washington County, near Potosi, is set for tomorrow, Friday, March 6. S & A Equipment & Builders, working with the Missouri Department of Transportation, plan to move to the second half of the project. The first half of the bridge is complete, and the contractor now plans to shift traffic to allow them to work on the other side of the bridge. Temporary signals will remain in place to direct traffic through the newly configured work zone. The project was expected to be completed in September 2025 but has experienced several delays. The contractor plans to have the second half completed, temporary signals removed, and the roadway reopened to two-way traffic by the end of May 2026. As with this and all construction, schedules are subject to change.
