We’re adding flashing yellow left-turn arrow traffic signals at intersections throughout Issaquah.
The flashing yellow left-turn arrow signal is a traffic management tool aimed at keeping traffic moving and increasing safety while reducing delays and fuel consumption.
The signal display more clearly indicates to drivers when it’s OK to make left turn across traffic. Remember: A flashing yellow means to turn with caution.
Work is starting in June and is scheduled for completion by November. The majority of work will occur at night, with no daytime lane closures planned.
As part of this project, seven signals will be converted to flashing yellow arrows:
- Northwest Maple Street and 12th Avenue Northwest
- Northwest Maple Street and the Issaquah Transit Center
- Newport Way Northwest and the Issaquah Transit Center
- Southeast Issaquah-Fall City Road and Southeast Black Nugget Road
- Northwest Gilman Boulevard and Fourth Avenue Northwest
- Front Street South and Second Avenue Southeast
- Northeast Discovery Drive and Eighth Avenue Northeast
Several existing traffic signals — including the intersection of Front Street and Sunset Way — already operate with a flashing yellow left-turn arrow.
Here’s how it works: In most locations, the flashing yellow arrow display will be part of a four-arrow display. At some locations, a three-section signal head may be used to display the flashing yellow arrow.
