North Issaquah: Road Improvements
We're undertaking a series of road improvements to relieve traffic congestion in North Issaquah — the area generally bounded by East Lake Sammamish Parkway Southeast, Southeast 56th Street/Northwest Sammamish Road, 17th Avenue Northwest and Interstate 90.

Current Conditions

Several roads in the area are operating at — or near — capacity, impacting the mobility of shoppers, visitors, employees and freight deliveries. In addition, commuters traveling through the area also experience significant delays, especially during rush hours.

Road upgrades could significantly help mobility and economic development in North Issaquah.
North Issaquah roadway network improvements include three separate projects:

East Lake Sammamish Parkway Southeast
East Lake Sammamish Parkway Southeast was widened between Southeast 56th Street and Southeast Issaquah-Fall City Road (see map).

Southeast 62nd Street
Southeast 62nd Street will be
widened between East Lake Sammamish Parkway Southeast and 221st Place Southeast (see map).

12th Avenue Northwest and 17th Avenue Northwest/SR 900 Intersection
The project will improve the intersection of 12th Avenue Northwest and 17th Avenue Northwest/SR 900 (see map). The design, permitting and right of way acquisition is planned to be complete by 2020.
