Districts Impacted
The Missouri Route 179 bridge over Rock Creek in Cole County, between Jamestown and Jefferson City, is slated for rehabilitation work in 2026. Built in 1936, the supporting structure is in good condition, but the driving surface has deteriorated and needs to be replaced.
The proposed plans call for closing Route 179 with a signed detour throughout construction.

PUBLIC MEETING
An in-person public meeting will be held on Tuesday, July 29, 2025, at the Centertown City Hall from 4:30 to 6 p.m. Members of the project team will be on hand to answer questions, provide information, and receive direct feedback on construction staging 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 1,500 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. The plans for the new deck, which will be the same width as the existing structure, include new approach pavement and installing new guardrail.
This project is not expected to require any new right-of-way acquisition.
The estimated total cost (engineering and construction) for this project is $829,000. This cost may change.
During the two-week comment period running July 22 – Aug. 5, 2025, the community and interested parties will have multiple avenues to learn about, ask questions, and submit input regarding the planned work and associated traffic impacts.

The project is currently scheduled to be part of MoDOT's December 2025 letting when contractors may submit competitive bids. The Missouri Highways and Transportation Commission may award the contract as part of their January 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 current plan is to close Route 179 during construction with a signed detour via Cole County Route T, U.S. Route 50, Cole County Route NN, and Cole County Route N.
At this time, the new bridge deck is expected to be complete by Dec. 1, 2026.
