Districts Impacted
The Route W bridge over Ashley Branch in Washington County is slated for a deck replacement in 2026. Built in 1963, the supporting structures are in good condition, but the deck is in need of replacement.
Construction will require a full roadway closure. No detour will be signed, but signs located well ahead of the closure will alert motorists to use an alternate route.
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 100 motorists who use the bridge on an average day while being responsible stewards of available funding.

Project Progress
The Missouri Department of Transportation is in the process of designing a new bridge deck on Route W over Ashley Branch River. The new bridge deck will be the same width as the existing structure. The project also includes new approach pavement and replacement of the object marker signs at the bridge ends.
This project is not expected to require any new right-of-way acquisition.
The estimated total cost (engineering and construction) for this project is $800,000. This cost may change.
During the three-week comment period that is from Oct. 28 – Nov. 18, 2025, the community and interested parties will have multiple avenues to ask questions, submit input, and learn about the planned work and associated traffic impacts.

The project is currently scheduled to be part of MoDOT's March 2026 letting, when contractors may submit competitive bids. The Missouri Highways and Transportation Commission may award the contract as part of their April 2026 meeting and, if the contract is awarded, a notice to proceed date will also be given. That is the earliest date the contractor may begin work.
Construction is expected to take place in 2026. The roadway is expected to be closed for 60 calendar days, subject to change.
No detour will be signed, but signs located well ahead of the closure will alert motorists to use an alternate route.
At this time, the new bridge deck is expected to be completed by Fall 2026.
