SR 530 - I-5 Interchange to SR 9 - Paving and ADA Compliance

Project news

Why is WSDOT repaving SR 530 in Arlington?

The pavement on SR 530 in Arlington, between I-5 and SR 9 is more than 20 years old. It is cracked, rutted and in need of repair from the 19,000 cars that travel this section of highway each day.

WSDOT contractor crews will grind the top layer and repave SR 530 between I-5 and the intersection of SR 9 with new asphalt.

Five sidewalk ramps at the SR 9 intersection will also be upgraded, creating a wider ramp and more gradual slope. The improvements will create better sidewalk connections for people of all abilities.

What can drivers expect?

SR 530 will be reduced to a single lane during overnight hours in order to avoid daytime traffic backups. Flaggers will be on site to alternate traffic.

The End Result

  • Once the project is complete, SR 530 will be free of wheel ruts and cracks, which can collect water and reduce traction.
  • Sidewalk users will have new ramps with wider and more gradual slopes.

Needs & Benefits

  • Preservation: Grinding, eliminating ruts and repaving improves the driving surface and extends the lifespan of the roadway.
  • Economic: The new pavement reduces the need for emergency repairs, which are costly to taxpayers and can cause additional congestion. 
  • Safety: Improving the highway surface eliminates and helps prevent future potholes, cracks and wheel ruts where water can collect. This gives drivers a safer, smoother ride. Reconstructed sidewalk ramps at intersections create better connections for people of all abilities.
