We are repaving about three miles of State Route 520 in sections between 108th Avenue Northeast and West Lake Sammamish Parkway.
This project also will repave four bridges, 10 ramps, replace bridge joints, place new pavement markings, and electronic vehicle detection equipment.
Why is WSDOT
repaving SR 520 between 108th Avenue Northeast and West Lake Sammamish Parkway?
Sections of SR 520, as well as 10 ramps that connect to the highway, are in need of repairs. Most of these sections and ramps were last paved 15 to 20 years ago. They now have ruts and cracks from carrying up to 100,000 vehicles every day. Contractor crews will grind down and repave these areas with asphalt to create a smoother, long-lasting surface. This work will reduce annual repair and maintenance costs.
The End Result
Repaving these segments of SR 520 extend the useful life of the pavement and increase safety for the more than 100,000 drivers who use this part of SR 520 every day.
- This project will extend the life of the highway and reduce annual maintenance costs.
- Drivers will have a smoother ride.
