JEFFERSON CITY, Mo. – The closure of Missouri Route 47 bridge over Mill Creek in Washington County, northeast of Potosi, near Cadet, has been postponed one week. Pending the delivery of materials, UDT, LLC, working with the Missouri Department of Transportation, now plans to close Route 47 at the bridge on Monday, Sept. 15, 2025, to complete the bridge rehabilitation project, which is expected to continue through mid-November.
While the supporting structures are in good condition, the 60-year-old bridge deck is in poor condition and needs to be replaced. The new deck bridge will be wider than the existing structure, the bridge rails will be updated, and new guardrails will be installed at the bridge ends. During the bridge deck replacement, the roadway will be closed, and a signed detour will direct motorists to use Missouri Route 67, Missouri Route 8, and Missouri Route 21.
