Northbound SR 529 will be closed at the Steamboat Slough Bridge, 24 hours a day, from 11 p.m. Friday, May 2, to 11 p.m. Tuesday, May 6, for mechanical work on the bridge. People will be able to use northbound SR 529 to go to Smith Island, but will need to leave the island via southbound SR 529. Vehicles over 11 feet tall need to exit at 28th Place Northeast because there is a low clearance bridge at 40th Place Northeast, the only other northbound SR 529 exit before Steamboat Slough.
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.
