HOBART – Travelers who use westbound State Route 18 during the overnight hours should plan ahead for delays beginning Sunday, May 12.
Contractor crews working for the Washington State Department of Transportation will close all lanes of westbound SR 18 at the Issaquah-Hobart Road overpass from 10 p.m. Sunday, May 12, to 5 a.m. Monday, May 13. This overnight closure will give crews room to safely set temporary concrete barriers before beginning around-the-clock bridge deck repair work.
At 5 a.m. Monday, a single lane of westbound SR 18 will open to travelers across the overpass, compared to the normal two-lane configuration. This temporary change will remain in place around-the-clock for approximately 65 days as crews work to repair and repave the Issaquah-Hobart Road bridge deck. When the work is complete in mid-July, the highway will return to the normal two-lane westbound configuration.
Westbound SR 18 detour
During the full closure, travelers will use the Issaquah-Hobart Road off- and on-ramps to bypass the work zone, with a uniformed police officer directing traffic at the intersection.
Future overnight closures
This is the first of up to eight overnight closures of westbound SR 18 as crews work to complete this important preservation project. The remaining overnight closure dates will be announced as the project moves forward. For up-to-date information, check the King County construction page or sign up for weekly email updates.
