WSDOT replaced a retaining wall on Issaquah-Hobart Road under SR 18 that was damaged by the floods in January 2009.
The new wall extends further than the original wall to prevent more damage to Issaquah-Hobart Road. Crews also replaced the damaged roadway shoulder, barrier and guardrail.
The new, larger retaining wall will better support Issaquah-Hobart Road and prevent future flood damage. New barrier and guardrail will improve safety.
