Missouri Route 43 Bridge Closure for Rehabilitation: What Drivers Demand to Know

Drivers in Jasper County, Missouri, should prepare for significant disruptions beginning the week of March 9, 2026, as the Missouri Route 43 bridge over the North Fork Spring River north of Joplin closes for a major rehabilitation project. The closure, expected to last up to 160 days, will necessitate detours and impact approximately 3,200 vehicles that daily cross the bridge.

Project Details and Timeline

The Missouri Department of Transportation (MoDOT) announced the closure to facilitate comprehensive repairs to the aging structure, originally built in 1971. The project involves removing and replacing the bridge deck, painting the bridge girders, and adding new pavement markings and object markers.

According to MoDOT, the contract completion date for the entire project is December 1, 2026. More information about the project can be found on the MoDOT website.

Traffic Impacts and Detour Information

All lanes of Missouri Route 43 will be closed during the rehabilitation. While drivers will maintain access to the bridge entrances, through traffic will be prohibited.

MoDOT will direct drivers along a signed detour utilizing Route 43, Missouri Route 96, Missouri Route 171, and Jasper County Route M. Drivers are strongly encouraged to explore alternate routes to avoid potential delays. MoDOT’s Traveler Information Map provides real-time updates on road closures and traffic conditions.

Broader Bridge Rehabilitation Project

This project is part of a larger initiative to rehabilitate several bridges in the region. Work on the Missouri Route 43/Spring River bridge will commence upon completion of the North Fork Spring River bridge repairs. Rehabilitation of the Jasper County Route M/Duval Creek bridge was completed last fall.

Project Costs and Contractor

The total project cost is $3.2 million. West Plains Bridge & Grading LLC, based in West Plains, Missouri, is the prime contractor for the rehabilitation work.
