This closure is part of MODOT’s project for upgrades to the Interstate 55 corridor in Jefferson County.

Last weekend, crews worked on the southbound I-55 loop ramp to northbound U.S. route 67. The intent of the project is to reduce the morning rush hour congestion by adding a lane, addressing 27 bridges, and changes to three major interchanges.  

The totality of the project is expected to wrap up in December of 2026 per MODOT.org. For more information on the full project, visit https://www.modot.org/interstate-55-corridor-upgrades-jefferson.
