Over the next few weeks, the city will be installing and testing its new "Traffic Signal Intelligent Transportation System" along 228th Avenue between Issaquah-Pine Lake Road and Northeast 12th Place (just north of the Safeway shopping center). The new system will measure real-time traffic loads, time the lights accordingly, and maximize the efficient flow of vehicles.

While installation and testing is taking place, drivers may notice irregularities and malfunctions from time to time. If you see a problem during regular office hours, please contact the City of Sammamish Public Works Department at 425-295-0565. During off hours, please contact King County signal maintenance at 206-296-8100.

Thanks for your patience!
