New HAWK pedestrian crossing signal to land in Washington County

A new type of mid-block pedestrian crossing signal will be activated for the first time on a Washington County-maintained roadway as part of the 170th Avenue and Florence Street Pedestrian Improvement Project.

The High-intensity Activated Crosswalk (HAWK) is a button-activated signal that stops drivers with a red light and allows pedestrians to cross. Its timing can be coordinated with other nearby signals to keep a steady flow of traffic. Research shows that HAWK signals are highly effective at getting motorists to yield for pedestrians.

HAWK signals may look new to some motorists. For pedestrians, it will look like a normal crossing signal. Here’s what you’ll see:

Drivers:

  • The signal is pedestrian-activated. When the lights are dark, drive as normal. Always keep an eye out for pedestrians when behind the wheel.
  • When activated, the signal will flash yellow and then turn solid yellow. Slow down and prepare to stop.
  • When the signal is solid red, stop! When the light flashes red and the crosswalk is clear, you can proceed.

Pedestrians:

  • When ready to cross, press the button. Wait while the orange DON’T WALK signal is lit.
  • Cross when you see the WALK signal.

The HAWK signal at 170th Avenue and Florence Street is expected to be activated winter 2024. See project updates. A second HAWK signal will be installed as part of the 185th Avenue and Ewen Drive Pedestrian Improvement Project, and is expected to be activated summer 2024.
