SR20 Closed Between Newhalem and Diablo Due to Rockslide

Newhalem, WA – A rockslide near milepost 121 has closed both directions of State Route 20 between Newhalem and Diablo overnight.

According to a release from the Washington State Department of Transportation (WSDOT), crews have closed State Route 20 at Milepost 121.  They do not currently have an estimated time for the reopening of the highway.

Travelers are not currently able to go around the slide due to the amount and size of the rocks that fell.

WSDOT crews are bringing in heavy equipment to break up the rocks and work to remove the debris from the highway.

The North Cascade Winter Closure is still in effect and WSDOT representatives say the closure does NOT affect the State Route 530 detour via State Route 20.
