Detour Drive

Updated: January 8, 2021

This web page is a starting point to help you move around your neighborhood and across the Duwamish. Please check back soon for additional resources. 


Closure of the West Seattle High-Rise Bridge has created congestion and air pollution for people living along detour routes in Duwamish Valley neighborhoods, like Highland Park, Roxhill, South Delridge, Roxbury, Georgetown, South Park and SODO.

If at all possible, finding other options to reach your destination, like walking or wheelingbiking or scootingriding the bus or water taxiridesharing, or staying local, could save you the headache of sitting in traffic and protect the health of neighbors living in impacted communities. 

For the trips you're unable to skip or flip, check out the traffic cameras and think about taking your trip during off-peak hours.

Drive Safe

Speeds that kill pedestrian

The speed limit on all residential (non-arterial) streets is 20 MPH. The speed limit on arterial streets is 25 MPH, unless otherwise posted.

Speed is the critical factor in the severity and frequency of crashes and hurting or killing people.

Look out for pedestrians and other travelers.

Drivers are required to allow people walking, wheeling, biking, an scooting to cross the road within marked AND unmarked crosswalks.

Slow down and follow the speed limit.
