Project Summary
The Washington County Route 8 bridge over the Union Pacific Railroad was built in 1969. While the supporting structures are in good condition, the driving surface has deteriorated, is in poor condition, and needs replaced. The new bridge deck will have new drains, bridge approaches added, and new, updated guardrail installed.
Project Progress
The Missouri Department of Transportation and its consultant have designed a new deck to extend the functional life of the bridge.
The estimated cost for these improvements, including engineering and construction, is $2.7 million. This cost may change.
The project was part of MoDOT’s August 2024 letting when contractors submitted competitive bids. The Missouri Highways and Transportation Commission awarded a $2,125,614.69 contract for the project at their September 2024 meeting to S & A Equipment & Builders. The contract was given a notice to proceed date of Oct. 7, 2024. This is the earliest date the contractor may begin work.
Route 8 over the Union Pacific Railroad will remain open during construction. The current plan is to stage construction, so that only one half of the bridge is closed at a time, with temporary signals in place to direct traffic. Construction is scheduled to begin March 3, 2025. The contractor will have 205 calendar days to complete the project once construction has begun.
