Prepare for significant traffic impacts citywide during a six-day full closure of East Lake Sammamish Parkway Southeast.
The closure has the potential to produce some of the worst congestion in recent memory.
All drivers should have a plan for getting around Issaquah from June 13-19, 2017, as the Washington State Department of Transportation (WSDOT) closes a section of the parkway just north of the Interstate 90 off- and on-ramps to Front Street.
The parkway closes at 8 p.m. June 13 and is expected to reopen by 5 a.m. June 19. During the closure, crews will improve a fish passage along Issaquah Creek’s North Fork.
The closure will affect one of only four ways to cross I-90 in Issaquah.
Drivers can still access I-90 via Issaquah Highlands, State Route 900 and northbound Front Street (see map).
Significant traffic is expected along Northwest Sammamish Road. Plan ahead for delays near Costco, Pickering Place and the Issaquah Farmers Market.
The six-day closure will also affect the nearby East Lake Sammamish Trail/Issaquah-Preston Trail. Cyclists and pedestrians will need to use a slight detour (see map) to get around the work zone.
When completed, the project will improve stream flows for migratory fish.
