Dallas County – A project to replace the Dallas County Route M bridge over the Niangua River west of Conway is set to begin the week of January 15, the Missouri Department of Transportation said.
The project will begin with construction of a crossing installed across the Niangua River at Charity Access. The Niangua River will not be navigable downstream from the boat access.
Crews will CLOSE the bridge beginning the week of January 29 for up to 160 days, as they demolish the existing bridge and replace it with a new structure. In addition, the contractor will add new barrier walls, guardrail and new permanent striping.
This bridge was built in 1964 and is in a deteriorating condition. Approximately 570 vehicles cross the bridge daily.
Traffic Impacts:
- No down-river floating on the Niangua River from Charity Access beginning week of January 15
- Charity Access Area will remain OPEN to the public
- Beginning week of January 29, all lanes of Route M CLOSED where crews are working
- Drivers will have access to driveways and entrances on either end of the bridge, but will not be able to drive through the work zone
- Signs and message boards will alert drivers approaching the work zone
- Drivers should consider alternate routes during the project
- Check MoDOT’s Traveler Information Map for road closings/traffic impacts
Weather and/or construction delays could alter the work schedule.
This work is part of a three-year project to improve 25 bridges within 15 miles of I-44 across the Southwest District. Of the 25 bridges in the project, known as the I-44 Corridor Bridge Bundle, seven (7) are mainline I-44 bridges, five (5) are I-44 overpass bridges and the remaining bridges are on adjacent routes over various features. Sixteen (16) bridges will be replaced and nine (9) bridges will receive major rehabilitation work.
