The state Department of Transportation plans to close southbound Issaquah-Hobart Road Southeast under state Route 18 for a month starting Monday.
During the closure, crews will replace a retaining wall damaged by Holder Creek flooding in January 2009.
Traffic will be detoured onto westbound state Route 18 to 244th Avenue Southeast, onto eastbound state Route 18 and then back to Issaquah-Hobart Road Southeast. The project should wrap by late September.
Floodwaters washed away sections of a retaining wall supporting Issaquah-Hobart Road Southeast. In the aftermath, DOT maintenance crews placed large rocks to stabilize the wall.
Plans call for a pile wall longer than the original, plus replacements for the damaged roadway shoulder, barrier and guardrail.
In May, DOT officials awarded a $2 million contract to Kent-based SB Structures to complete the project.
