City of Issaquah issued the following announcement.
Crews are working to build a new, four-way traffic signal at the intersection of Northwest Gilman Boulevard and Northwest Juniper Street.
Drivers should expect delays in both directions of Northwest Gilman Boulevard from 9 a.m.-3 p.m. weekdays starting Nov. 23, 2020. The project, and traffic impacts, will last several months. Detours will be provided for pedestrians.
In addition to making this intersection safer for vehicles, the project will also improve accessibility for pedestrians and cyclists at the Three Trails Crossing (East Lake Sammamish Trail, Rainier Boulevard Trail and Juniper Street Trail).
