Traffic Signals
Responsibility for traffic and pedestrian signals is a confusing subject. Most signals located within city limits are the responsibility of the City of Issaquah.

However, all signals on SR900 or at the "ON" and "OFF" ramps to I-90 are the responsibility of the Washington State Department of Transportation. They can be reached at 206-442-2110.

You may report a traffic signal malfunction online or by calling 425-837-3200.
