The Washington State Department of Transportation (WSDOT) reports that upgrades to I-5 through DuPont and Joint Base Lewis-McChord have entered a new phase of construction.
On Wednesday, October 23, crews working for the WSDOT shifted northbound lanes of I-5 between Mounts Road and 41st Division Drive near JBLM’s main gate.
Crews have also closed I-5 ramps to and from Center Drive, Steilacoom-DuPont Road and 41st Division Drive. There will be no more than two consecutive ramps closed at a time. A signed detour will direct travelers to the next nearest ramp.
All lanes and ramps will reopen by 4:30 a.m. the following day.
On Thursday, October 24, travelers will notice northbound lanes adjusted from their current location between Center Drive and the existing HOV lanes at JBLM.
People are encouraged to watch for temporary changes to the roadway.
Keeping I-5 Open During Major Construction
Crews are creating a new work zone in the I-5 median. The new work zone allows crews to:
- Build new northbound and southbound I-5 HOV lanes.
- Advance work on the new I-5 bridge over Pendleton Avenue.
- Continue work on the new half diverging diamond interchange at I-5 and Steilacoom-DuPont Road and a new roundabout.
The project is scheduled to be complete late fall 2026.
Whenever near work zones please:
- Slow down – drive the posted speeds, they’re there for everyone’s safety.
- Be kind – workers are out there helping to keep everyone safe and improve the roadways.
- Pay attention – both to workers directing traffic and to fellow travelers.
- Stay Calm – expect delays, leave early or take alternate routes if possible.
