Crosswalk placement is managed by the City of Seattle’s Department of Transportation. You can learn about their criteria and evaluation for determining crosswalk marking strategies and practices at their website.
SDOT takes into account a variety of factors when determining whether a crosswalk should be marked, including the number of lanes that pedestrians must cross, the proximity of the location in question to existing traffic signals, and the number of pedestrians who cross the street consistently at that location all help to answer the fundamental question that we ask: “Will a marked crosswalk benefit pedestrians?”
Contact SDOT through e-mail WalkAndBike@Seattle.gov or call 206-684-7583. Provide the exact location, the number of lanes in the roadway, and as much information as possible about the nature of the concern.
