Contractor crews widening Interstate 5 along Joint Base Lewis-McChord are creating a work zone that will allow them to build two new overpasses as part of the Interstate 5 -- Steilacoom-DuPont Road to Thorne Lane Corridor Improvements.
The work requires several overnight closures of the southbound I-5 Thorne Lane on- and off-ramps. Crews are also advancing work at the new Berkeley Street overpass and widening I-5 from Thorne Lane to just south of 41st Division Drive.
Daytime drivers will see shoulder closures in both directions of I-5 from Steilacoom-DuPont Road to Thorne Lane.
