Overview
Starting in spring 2011, we will widen SR 522 to four lanes between the Snohomish River and just south of the 179th Avenue SE overpass in Monroe, build a new bridge across the Snohomish River and construct a median to separate opposing lanes of traffic
As part of a separate project, we will build a new direct ramp from eastbound SR 522 to eastbound US 2.
Why is WSDOT
widening SR 522 between the Snohomish River and US 2 in Monroe?
Drivers experience heavy congestion on this section of SR 522. Widening the road into a four-lane divided highway will reduce congestion and the likelihood of collisions.
The End Result
SR 522 will be four lanes between the Snohomish River and US 2 in Monroe. Crews will also build five bridges for the new roadway, including a 1/3 mile bridge across the Snohomish River, and a new direct ramp from eastbound SR 522 to eastbound US 2.
Project Benefits
• Safety. We will build a median to separate opposing lanes of traffic, reducing the potential for head-on collisions.
• Congestion relief. We will double the capacity of 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.
