Why is WSDOT Repaving SR 530 in Arlington?   
The pavement on SR 530 near 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 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 during construction?
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

The new pavement will reduce the need for costly emergency repairs, create a smoother driving surface and preserve the road for years to come.

New sidewalk ramps will create a more gradual transition, making it easier for people of all abilities to use the sidewalks.
