Needs & benefits

WSDOT contractor crews will grind and pave almost 4 miles of State Route 522 from just east of SR 9 to the Fales Road/Echo Lake Road off-ramp. They will also add 3 miles of raised striping along the shoulders in both directions to improve safety from west of Fales Road/Echo Lake Road to the Snohomish River Bridge. In addition to the highway work, eastbound SR 522 across the Snohomish River Bridge will also be repaved. This work will require nighttime full closures of the eastbound Snohomish River Bridge for two weekends.

With up to 34,000 vehicles using SR 522 daily, the pavement is worn out with ruts and cracks that can lead to potholes. This stretch of SR 522 was last paved in 2001. Asphalt is generally intended to last 15 years. Repaving the road will improve the driving surface for travelers and reduce the chances of costly emergency repairs.
