Delridge Way SW presents opportunities and constraints when planning for street and transit improvements. We considered these when developing early concepts to balance the needs of everyone who uses the corridor, whether they're in a bus, a car, walking, or riding a bike.


  • Walkable business areas – Sidewalks along Delridge Way SW are generally walkable. Additional improvements could build off what already exists to transform the corridor into a walkable destination.
  • Connections to trails and nature – There are multiple connections from Delridge Way SW to the Longfellow Legacy Creek Trail. Enhancing connections to the trail could leverage the trail network as a supplemental route for people walking and biking along the corridor.
  • Vehicle speeds – Current street conditions and intersections enable higher speeds that can create conflicts between motorized vehicles and the corridor's most vulnerable users, including people walking and biking. Improving intersections throughout the corridor can help manage speeding and conflicts.
  • Existing neighborhood greenways – There are two neighborhood greenways parallel to Delridge Way SW. There are opportunities to strengthen connections to these greenways and Delridge Way SW.


  • Narrow street width – Delridge Way SW narrows considerably at the south end of the corridor. This presents challenges as we look to integrate facilities for people who bike and walk, along with adding improvements to speed up bus travel.
  • Disconnected street grid – Limited street connections and steep hills limit links into neighborhoods and make it difficult for people to walk or bike to businesses and transit.
  • Utility poles – Seattle City Light runs a high capacity electric line along certain portions of Delridge Way SW. Potential improvements will need to accommodate the current location and size of these poles, which may limit our ability to accommodate travel lanes, bike facilities, and sidewalks in certain areas along the corridor.
  • Poor centerline pavement – A good portion of Delridge Way SW has a center turn lane. During our review of the pavement, we found that the center turn lane could not withstand high volumes of traffic due to its current condition. This meant we could not convert the center turn lane into a general travel lane.
