Project Summary

Beginning August 12, 2024, the intersection where Route 22 meets Routes 124 and 151 will be reconstructed into a roundabout.

The intersection of Missouri Routes 22, 124, and 151 in Centralia needs improvements. The existing four-way intersection creates less-than-optimal safety conditions for traffic. By installing a roundabout, the potential impact points for crashes, especially t-bone crashes, is greatly reduced, lowering the chance of a serious or fatal crash. The plans include improvements that will enhance safety, drivability, and traffic flow. The project is expected to be finished by 2025. 

 

Project Details

When: 
This project is scheduled to begin August 12, 2024, and be complete by 2025. 

Cost: 
The estimated construction cost for the project is $1.1 million. 

Work Taking Place

The project plans include constructing a roundabout at the intersection of the Missouri Routes 22, 124, and 151. The proposed intersection layout will improve traffic flow and safety at the intersection.

Traffic Impact:
Route 151 will be temporarily closed for up to 28 calendar days to construct the north portion of the roundabout and will have a signed detour. Routes 22 and 124 will be staged to construct the remaining portions of the roundabout and at least one lane will remain open.

Project Letting, Award, and Notice to Proceed

The project was part of MoDOT's May 2024 letting when contractors submitted competitive bids. The Missouri Highways and Transportation Commission awarded a $1,219,030.30 contract to Capital Pavine & Construction, LLC as part of their June 2024 meeting. At that time, the contractor was given a notice to proceed date, which is the earliest date the contractor may begin work.

Project Construction, Traffic Impacts, and Completion

Construction began Aug. 12, 2024, with the closure of Route 151 in order to construct the northern half of the roundabout. On Sept. 5, 2024, the contractor reopened Route 151.

Construction on the southern half of the roundabout continues. By contract, the contractor has 72 calendar days in which to complete the project.

Project News and Updates

Project Overview

FREQUENTLY ASKED QUESTIONS

Why is MoDOT replacing the Route 22 Intersection?

The existing intersection has a complicated 4-way juncture whose safety falls short of optimal standards. The new structure will be up to current standards and improve the drivability and safety for motorists.

The project will involve staged single lane closures in addition to Route 151 being briefly closed with a signed detour.
