Project Summary
The Missouri Route 47 bridge over Mill Creek in Washington County, north of Potosi, was constructed in 1965, is narrow, and the deck is in poor condition. A project is currently in the planning and design stage that will replace the current bridge deck with a wider one, bring the bridge rails up to current safety standards, and install new guardrail at the ends of the bridge. These improvements will enhance safety, drivability, and traffic flow.
Project Progress
The Missouri Department of Transportation is currently designing functionality and safety improvements, including increasing the bridge width from 24 to 26 feet with a new deck, installing new rail on the bridge and installing new guardrail at bridge ends.
As of July 17, 2024, the estimated cost for these improvements, including construction and engineering, is $930,000. This cost is subject to change.

The project is currently scheduled to be part of MoDOT's January 2025 letting when contractors may submit competitive bids. The Missouri Highways and Transportation Commission may award the contract as part of their February 2025 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.
At this time, construction is anticipated to begin in summer 2025 and be complete by Dec. 1, 2025. The current plan will close Route 47 during the construction of the new bridge for up to 110 calendar days and a signed detour will be in place using Routes 67, 8, and 21.

FREQUENTLY ASKED QUESTIONS
Why is MoDOT replacing the bridge?
The existing Route 47 bridge over Mill Creek was built in 1965, and the deck needs to be replaced. The bridge width, bridge rail, and guardrail need to be upgraded. The deck is in poor condition, but the substructure is in good condition. The new bridge deck and rail will improve the drivability and safety for motorists.
How will the new bridge construction affect traffic?
The current plan will close the bridge to all traffic through the completion of the project up to 110 calendar days. A signed detour will be posted over Routes 67, 8, and 21.
