Districts Impacted
The Route 8 bridges over Allen Creek, Mid Fork Fourche a Renault, and North Fork Fourche a Renault in Washington County, east of Potosi, are slated for deck replacements in 2026. All three bridges were built in 1965. The supporting structures are in good condition, but the decks need to be replaced.
All three bridges are expected to remain open during construction but narrowed to one lane with temporary traffic signals directing motorists through the work zone.
Public Meeting
An in-person public meeting will be held on Tuesday, Nov. 4, 2025, at the Washington County Chamber of Commerce from 4:30 to 6 p.m. Members of the project team will be on hand to provide information and answer questions from the community. There will be no formal presentation, so members of the public can come and go as they please. By participating and commenting, the public can help MoDOT determine what best serves the needs of the roughly 4,000 motorists who use the bridges on an average day while being responsible stewards of available funding.
