Rock Crusher Hill speed reduced, again
Effective immediately, the speed limit on US 101 south of Artic at Rock Crusher Hill is reduced from 55 mph to 25 mph. Recent heavy rains have caused the recurrence of chronic roadway settlement along a 200-foot stretch of highway.
Maintenance crews have installed additional signs to warn motorists to slow down as they drive through the area.
This closely-watched section of highway is located on top of an active landslide and has a history of pavement settlement. Last summer, the speed limit was temporarily reduced to 25 mph until crews could repair and eventually repave the area. They also installed additional overhead lighting to help motorists more clearly see the roadway.
Previously, WSDOT installed a culvert into the hillside to divert water away from the road. Despite efforts to reduce land movement, the slide continues to move and disrupt the highway surface. Patching and paving efforts, seen as only temporary repairs by WSDOT, will continue until funds for a permanent repair can be identified.
The 25 mph speed limit will remain in effect until further notice.
