DUPONT – Travelers who use the Mounts Road on-ramp to southbound Interstate 5 will need to plan for extra travel time during the week of Oct. 5 and Oct. 12.
Crews will close one lane of southbound I-5 near milepost 117 and the Mounts Road on-ramp to southbound I-5 on the following nights:
- Wednesday, Oct. 7, from 9 p.m. to 6 a.m. Thursday, Oct. 8.
- Thursday, Oct. 8 from 10 p.m. to 6 a.m. Friday, Oct. 9.
- Monday, Oct. 12 from 9 p.m. to 6 a.m. Tuesday, Oct. 13.
During the overnight ramp closure, travelers will follow a signed detour using northbound I-5 to exit 119 Steilacoom-DuPont Road and back to southbound I-5.
The lane and ramp closures are needed to create a work zone so Amtrak-contracted crews can remove contaminated soil from the 2017 Amtrak train derailment site.
