Drivers should plan ahead for overnight closures in Issaquah this week as crews finish permanent striping on the SR 900 widening project.

Drivers can expect single-lane closures on eastbound and westbound SR 900 from 8 p.m. to 5 a.m. Monday through Thursday, Aug. 2–5. On Wednesday and Thursday nights, crews will also close the westbound I-90 off-ramp to SR 900 at 8 p.m. Drivers will follow a signed detour using the exit to West Lake Sammamish Parkway. The ramp will reopen by 5 a.m. the following morning. This work is weather dependent.

This work is part of the SR 900 – SE 78th Street to Newport Way widening project. Crews opened the new SR 900 lanes to traffic this spring.
