Starting at 8 p.m. Monday, March 24, crews will begin lane reductions on southbound I-5 approaching Steilacoom-DuPont Road (Exit 119) to shift traffic towards the median. A rolling slowdown begins at 11 p.m. for additional lane reductions. All lanes reopen at 5 a.m. the following morning. This work is weather dependent and may be rescheduled. See "what to expect" below for more information.
Project overview
This project is intended to help relieve chronic traffic congestion and improve mobility along I-5 near Joint Base Lewis-McChord. Crews will rebuild the Steilacoom-DuPont Road (Exit 119) interchange and extend I-5 HOV lanes to Mounts Road.
What to expect
Southbound I-5 traffic shifts
Crews are building two bridges between Pendleton Avenue and the Steilacoom-DuPont Road overpass. As work progresses, workers will temporarily shift lanes towards the median to make room for the bridge work zones.
