SR 530 Seattle City Light Access Road

 

Map of the Seattle City Light maintenance road.

This is a one-lane gravel road that will be used intermittently to provide access to and from Darrington during reconstruction of SR 530.

  • This road will be open for local access only 24/7. Please do not use this road unless you are local or have business ties in Darrington, Oso or Arlington.
  • Pilot cars will guide drivers through the route. Drivers will be escorted through westbound at the top of the hour, eastbound on the half hour.
  • Speed limit is 10 mph.
  • Drivers will not be allowed to stop or pull over along the road.
    Washington State Patrol troopers and private security staff will assist with escorting vehicles on the route.
  • Make sure you arrive early.

    Larger Vehicles
  • Vehicles over 105,500 lbs are not permitted
  • Trailers up to 24 feet, including horse trailers, and dump pup trucks are allowed.
  • School buses and RVs are allowed.
    Logging trucks are allowed around the clock.
  • Semi-trucks up to WB 40 are allowed.
  • Drivers should be able to negotiate their vehicle over steep grades of up to 18%.
    Drivers should also be skilled and familiar with the area and road due to a tight corner on the west side.

Trips through the local access road are averaging between 15 and 20 minutes. But those times could increase if non-local traffic begins using the route for recreational trips.

Late-night and early morning trips will remain on the established schedule to accomodate the material removal trucks and crews.
