Mussel Fork River and Overflow bridges on U.S. 24 west of Keytesville set to be replaced

KEYTESVILLE, Mo. – Located just west of Keytesville on U.S. Route 24, the Mussel Fork River and Mussel Fork River Overflow bridges have been serving motorists since 1927. A replacement project to bring both Chariton County bridges up to current standards will be led by contractors from Don Schneider’s Excavating Company, Inc., working with the Missouri Department of Transportation. Crews plan to begin construction this coming Monday, June 3, 2019.

Contractors will begin work on Mussel Fork River Bridge, which will remain open for construction, as the new bridge will be built on a new alignment to the north of the current structure. This new alignment will eliminate most of the roadway curvature allowing for longer, safer sight distance.

Crews will use excess fill material from the old Mussel Fork River Bridge to create a one lane, gravel bypass to be used during the Mussel Fork River Overflow Bridge replacement. The overflow bridge will be replaced with a culvert along the current bridge alignment.

Two sets of traffic signals will be used to guide motorists through the work zones of each bridge with a reduced speed limit of 25 mph. Contractors plan to have the bridges open to two way traffic by the end of 2019 with all work completed by early 2020.
