The deck of the Caldwell County Route 116 bridge over the UP Railroad, located between Polo and Cowgill, was in poor condition. A project in spring of 2023 replaced the bridge deck and brought the bridge railing up to current standards.

Project Progress

Planning & Design Phase

MoDOT's Planning and Design team, along with a consultant team, designed a project which will replace the bridge's deteriorating deck, including bridge joints. The project will also bring the bridge's railing up to current standards.

Contract Letting, Award & Notice to Proceed

The project to replace the deck of the Caldwell County Route 116 bridge over the UP Railroad was bundled with three other bridge deck replacements and two bridge rehabilitations. These projects are in Caldwell, Carroll, Grundy & Livingston counties. The project for these six bridges was part of the October 2021 letting where contractors submitted competitive bids on the project bundle. The Missouri Highways and Transportation Commission awarded the $4,626,301.91 project to Capital Paving & Construction, Inc. at their November 2021 meeting. At that time they gave the contractor a January 3, 2022 Notice to Proceed. This is the earliest date the contractor could begin work.

Project Construction

The contractor has been working with the UP Railroad and MoDOT began construction on Feb. 20, 2023 and reopened the roadway on May 22, 2023. 


Frequently Asked Questions:

Q: Why is MoDOT closing the road during construction?

A: MoDOT strives to be a good steward of taxpayer money. By closing the roadway at the UP Railroad Bridge, the contractor will be able to work more efficiently within a shorter construction period, saving taxpayer dollars and reducing the time period construction will affect motorists.


Q: What is the detour during the bridge closure?

A: During construction, truck traffic will be directed over a signed detour on Route 13, U.S. Route 36 and Route A. Local traffic will be directed over a signed detour on Routes 13, F and B. 


Q: Who can I contact if I have further questions?

A: Questions about the project may be directed to MoDOT's Customer Service team at or by phone at 888 ASK MODOT (1-888-275-6636).
