I-5 - Mounts Rd. to Steilacoom-DuPont Rd. - Corridor Improvements

Project overview

To relieve chronic traffic congestion and improve mobility along I-5 in the vicinity of Joint Base Lewis-McChord, WSDOT is proposing to rebuild the interchange of Steilacoom-DuPont Road (Exit 119) and adding HOV lanes to I-5. This will support congestion relief on I-5 during peak traffic periods while maintaining access to neighboring communities and JBLM. The proposed build alternative also includes grade separation of the roadway over the railroad.
