The Washington State Department of Transportation (WSDOT) reports that travelers will notice the opening of new I-5 high occupancy vehicle lanes in the DuPont area. The northbound diamond lane extension allows people to pick up the new HOV lane at Mounts Road. The new southbound I-5 HOV lane extends beyond Steilacoom-DuPont Road.

I-5 HOV Lane Benefitsย 

HOV lanesย prioritize the movement of people over vehicles and encourage commuters to carpool or use transit. This is the third Washington State Department of Transportation project related to widening I-5 and creating new HOV lanes between DuPont and Lakewood.

About This I-5 Projectย 

While working to reduce congestion, theย projectย also helps improve mobility for people who travel between DuPont and Joint Base Lewis-McChord.

Improvements include:

  • A new overpass with a shared-use path between DuPont and JBLM that eliminates the need for DuPont travelers to stop for passing trains.ย 
  • Improved access to and from JBLM’s DuPont gate.
  • A new traffic signal on the southbound I-5 off-ramp to Mounts Road.
