DUPONT – Contractor crews working for the Washington State Department of Transportation will close lanes and ramps on northbound Interstate 5 in DuPont at the Steilacoom-DuPont Road interchange overnight Wednesday, Aug. 9 and Thursday, Aug. 10.
The closures allow Atkinson Construction to set barrier and re-stripe the northbound I-5 off- and on-ramps at Steilacoom-DuPont Road. This will create a work zone so crews can begin the I-5 Mounts Road to Steilacoom-DuPont Road Corridor Improvements project.
Work schedule is subject to change.
