Eastbound State Route 18 will close for three nights beginning Monday, July 8, for pavement repairs northeast of Maple Valley for pavement repairs. No eastbound traffic will be allowed east of Issaquah-Hobart Road or over Tiger Mountain summit during the work.
People traveling in the area will not be able to access Interstate 90 from eastbound SR 18 and will need to detour using the appropriate alternate route.
From 11 p.m. to 4 a.m. nightly Monday, July 8, through Thursday morning, July 11, contractor crews will grind down damaged areas of pavement along the 5-mile section of eastbound SR 18 between Issaquah-Hobart Road and Deep Creek and repair them with new asphalt. The work is weather-dependent and may be rescheduled.
Eastbound SR 18 detours
People heading eastbound should follow one of two detours during the closures:
Freight: All semi trucks and freight traffic should use northbound I-405 to eastbound I-90. Freight traffic should not use Issaquah-Hobart Road or Issaquah city streets, as these streets are unsuitable for freight traffic.
Passenger vehicles: Other vehicles may use northbound Issaquah-Hobart Road to northbound Front Street to eastbound I-90.
Westbound SR 18 repairs
After repairs are finished on eastbound SR 18, crews will switch and close the westbound SR 18 for two nights of pavement repairs. That weather-dependent work is scheduled between 11 p.m. Thursday, July 11, and 5 a.m. Friday, July 12, and at the same time, Monday night, July 15.
People heading westbound should follow one of two detours during the closures:
Freight: All semi trucks and freight traffic should use westbound I-90 to southbound I-405. Freight traffic should not use Issaquah city streets or Issaquah-Hobart Road, as these streets are unsuitable for freight traffic.
Passenger vehicles: Other vehicles may use westbound I-90 to southbound Front Street to southbound Issaquah-Hobart Road.
The SR 18 work is part of a regional pavement repair project working to create a smoother ride and help extend the lifetime of several highways.
