- Highway closures: Friday, May 17 - No closures of SR 522 for rock blasting and removal are planned through May 27.
- Check the construction report for all upcoming closures, including nighttime lane closures.
- See pictures of our recent work.
- Videos: Watch a video of our first three blasts and hear the project engineer and blasting supervisor explain the process. Watch a time-lapse video of crews setting girders for the 164th Street SE bridge.

In 2012-2014, we will widen more than four miles of SR 522 to four lanes from just west of the Snohomish River Bridge to 179th Avenue SE in Monroe. We will also build four new bridges, including a new bridge across the Snohomish River, add median barrier to separate oncoming traffic, build a roundabout at 164th Street SE, add a noise wall, build a wildlife crossing, and upgrade lighting and signing.
As part of a separate project, we built a new direct ramp from eastbound SR 522 to eastbound US 2.
Why is WSDOT
widening SR 522 between the Snohomish River and the city of Monroe?
Nearly 28,000 vehicles travel this stretch of SR 522 each day. Drivers experience heavy congestion and delays. Widening the road into a four-lane divided highway will reduce congestion and the likelihood of collisions. There were 100 collisions on this stretch of mainline SR 522 from 2006 to 2010, including three fatal collisions and four serious injury collisions. There were an additional 54 collisions at the SR 522/164th Street/Main Street interchange.
The End Result
SR 522 will be four lanes between the Snohomish River and US 2 in Monroe. Crews will also build four bridges for the new roadway, including a 1/3 mile bridge across the Snohomish River.
• Safety. We will build a median to separate opposing lanes of traffic, reducing the potential for head-on collisions. Improving traffic flow will also reduce the risk of congestion-related collisions, such as rear-end and sideswipe collisions. There were 39 rear-end collisions on this stretch of SR 522 from 2006 to 2010.
• Congestion relief. We will add capacity on this stretch of SR 522 to improve traffic flow and cut down on drive times. As part of another project, we will also add a new direct ramp from eastbound SR 522 to eastbound US 2 to help relieve congestion at the SR 522/US 2 interchange.
• Environment. We will build detention ponds to improve water quality. The ponds will collect and filter dirty rain water from the highway before it is released slowly into the area creeks, benefitting salmon and other wildlife. The ponds also reduce the potential for flooding in area creeks.
