April 12, 2017 UPDATE: SR 503 remains closed near Speelyai Bay Road . Contractors will begin the first phase of rock blasting work to remove a dangerous rock slab above the highway on Thursday, April 13. Once debris is removed, the area will be inspected to determine next steps. Additional work will likely include blasting and slope stabilization work. Watch a video of blasting preparation and an interview explaining the process.

March 17, 2017 UPDATE: Both directions of State Route 503, 20 miles east of Woodland remain closed due to a major debris slide blocking the highway. Due to heavy rainfall, the slope continues to move and there is concern of additional rocks and debris falling. Using drone technology, WSDOT geotechnical engineers inspected the hillside and are working to develop a permanent repair. At this time, it is still too soon to tell when the highway will reopen to traffic. Drivers should continue to use alternate routes. Watch drone video of the slide.
