SW Admiral Way and 59th Avenue SW

The Seattle Department of Transportation (SDOT) has selected three signals across the city to be converted to all-way stops. The conversions require reprogramming signals to flash red continuously and adding stop signs. Signal conversions at some intersections can improve overall throughput and safety. The signal conversions often improve the experience for pedestrians and bicyclists since they don’t have to a wait full light cycle to move through an intersection.

This isn’t the first foray into such signal conversions. In 2014, SDOT converted a signal at University Way NE and NE 40th St to an all-way stop. Lights at the intersection now blink red continuously and regular stop signs were added. NE 40th street provides an important east-west link between the main University of Washington campus and Burke-Gilman Trail. Four dormitories also flank the street west of University Way NE.

The three signalized intersections getting the conversion are spread across West Seattle, Licton Springs, and University District:

  • SW Admiral Way and 59th Avenue SW;
  • College Way N and N 95th Street; and
  • NE 50th Street and 17th Avenue NE.

The conversions should be complete before the end of September. SDOT will evaluate the performance of the street conversions over the following six months. Further refinements or changes could result during the initial conversion phase.

In 2015, I had suggested that similar signal conversions should be made on NE Campus Pkwy at Brooklyn Ave NE and University Way NE for many of the same reasons that SDOT modified University Way NE and NE 40th St. Are there any intersections that you think deserve an all-way stop instead of a full-fledge red/yellow/green signal?
