About West Marginal Way SW

Since the closure of the West Seattle High-Rise Bridge in March 2020, we’ve seen significant increases in the number and speed of vehicles driving along West Marginal Way SW. Acknowledging that West Marginal Way SW is a Major Truck Street that needs to accommodate large trucks, we are working to prioritize safety and mobility for everyone while accommodating increased traffic.  

This year, we will begin making the following safety and mobility improvements along this busy corridor:  

Signal and Pedestrian Pathway 

In 2021, we will build an interim pedestrian signal and painted crosswalk at the Duwamish Longhouse. This signal will increase safety for people crossing West Marginal Way SW. We are also designing a permanent signal in 2022. In addition, we will install a pedestrian pathway in 2021 on the west side of West Marginal Way SW between the Duwamish Longhouse and SW Idaho St. These projects are critically important to provide safe access for people walking to the Longhouse. 

Applying Vision Zero Principles to West Marginal Way  

While speeding has been reduced through lower posted speed limits and installation of radar feedback signs high speeds are still being observed. Further steps to reduce speeding on the corridor include a potential redesign of the roadway. Potential design options could also meet additional Reconnect West Seattle mobility goals. These goals include connectivity for people riding bikes and ensuring safe mobility and accessibility for freight vehicles  along the corridor and to nearby businesses. We have proposed a two-way protected bicycle lane in the southbound curb lane that would provide all ages and abilities bicycle connectivity from the Duwamish River Trail to the West Seattle Bridge Trail. We are still discussing additional freight access and mobility improvements with stakeholders and businesses.
