About this Project
The purpose of the project is to improve traffic flow and safety along the I-49 corridor in Jackson and Cass Counties. The project is scheduled to be let in November 2027 with construction beginning in Spring 2028. Detailed traffic impacts are yet to be determined, but it’s likely that lane closures would impact traffic flow during the project construction.
