I-5 - NB Marine View Drive to SR 529 - Corridor and Interchange Improvements

Project overview

To address congestion at the I-5/SR 528 interchange and on I-5 between Everett and Marysville, WSDOT will build a new roundabout at the I-5/SR 529 interchange, add new ramps from I-5 northbound to SR 529 and SR 529 to southbound I-5, and extend the I-5 northbound HOV lane from near US 2 to SR 529.

What to expect

The northbound I-5 HOV lane extension from Pacific Avenue in Everett to the Steamboat Slough Bridge in Marysville has opened. This portion of northbound I-5 now has three general purpose lanes in addition to the HOV lane.

The lanes of I-5 have been shifted between Marysville and Everett for construction, which will continue through spring 2025. People traveling between Everett and Marysville northbound and southbound on I-5 or SR 529 should plan for nighttime lane reductions between 9 p.m. and 8 a.m. 

The project will add a roundabout at the I-5/SR 529 interchange, a northbound off-ramp from I-5 to SR 529 and an on-ramp from SR 529 to southbound I-5, and a northbound HOV lane between Marine View Drive in Everett and SR 529 in Marysville.
