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
Construction plans and traffic effects are currently unknown. We will provide an update when the design process is complete.
The project will add a roundabout at the I-5/SR 529 interchange, a northbound ramp from I-5 to SR 529 and a ramp from SR 529 to southbound I-5, and a northbound HOV lane between Marine View Drive in Everett and SR 529 in Marysville.
