Crews built a larger, stronger retaining wall that will better withstand flooding.
Crews repaved a section of SR 18 that was removed to build the new retaining wall.
The high flow in Holder Creek in January 2009 washed away sections of the retaining wall.
The flooding also washed away part of the shoulder along Issquah-Hobart Road.
WSDOT maintenance crews placed large rocks to stabilize the wall until a permanent fix could be made.
