Overview
On Jan. 14, 2010, a large mudslide blocked all westbound lanes of SR 18 just west of SR 167 in Auburn. Crews cleared the slide, stabilized the slope and reopened the road to traffic within five days. In the summer, crews built a new 600-foot-long, 10-foot high containment wall to permanently protect the road from future slides. The wall extends east from the end of the existing containment wall near the truck climbing lane.

 | Improves Safety
The steep slope above SR 18 has a history of slides. The new containment wall will keep traffic and freight moving, and prevent any future slide debris from reaching the road.
