Webster County – Construction on the Webster County Route Y Bridge Replacement Project over the Niangua River between St. Luke Road and Willow Lane in Conway, beginning Monday, April 13, the Missouri Department of Transportation said.
Project Highlights:
- Provide an improved crossing of Route Y across the Niangua River in Webster County between St. Luke Road and Willow Lane
- The new bridge structure will:
- Decrease the frequency of roadway overtopping events
- Improve hydraulic conveyance through the new structure
- Decrease the buildup of debris and drift, reducing future maintenance
- The previous culvert was removed after it sustained damage from flash flood conditions that occurred in early June 2025
Traffic Impacts:
- Route Y CLOSED to through traffic at Webster County Route W and Route WW
- Local residents will have access to their property on either side of the closure; however, they will not be able to drive across the Niangua River
- Detour Routes: Webster County Route W and Route M
- Signs and message boards will alert drivers approaching the work zone
- Drivers will need to seek an alternate route to avoid the work zone
- Check MoDOT’s Traveler Information Map for road closures/traffic impacts
Weather and/or construction delays will alter the work schedule.
