Highland Park Way SW and SW Holden St Safety Improvements
Updated May 17, 2024
What's Happening Now?
Night work scheduled for May 20
We are adjusting the lanes on Highland Park Way SW and SW Holden St so freight trucks can make wider turns and avoid running over the sidewalk at the northwest corner of the intersection. To do this, we must remove the existing traffic markings and paint new ones. This process requires special equipment that is noisy, and we will be working outside normal construction hours.
When: Monday, May 20 | 6 PM – 4 AM. Please note that this work is weather and temperature dependent, so we may need to shift the date.
Where: We will be working on Highland Park Way SW and SW Holden St just north and west of the intersection.
What to Expect: We will be running equipment that sounds like a giant vacuum, but no vibration or banging is expected. Noisy work will be done by 10 PM. Alternating traffic lanes will also be closed, but there will always be one lane open for cars to get through.
New traffic signal is live at Highland Park Way SW & SW Holden St
The new permanent traffic signal is live at Highland Park Way SW and SW Holden St, contributing to improved safety and traffic flow.

This work included hanging traffic cameras to monitor and adjust the signal in real-time and installing traffic loops in the pavement on all four sides of the intersection so the signal can recognize when a person driving is waiting at the light. We also activated the crosswalk buttons on the sidewalks, so people can request a signal change when they need to walk across the street.

Project Overview & Design
Highland Park Way SW is a major north-south route in West Seattle, providing access to SR 99, SR 509, I-5, and the Duwamish Trail. It has been the site of several crashes and safety issues due to poor sight distances, high speeds, travel lane confusion, and a lack of pedestrian facilities like crosswalks. The Highland Park community asked for changes at this busy intersection and this project includes:
- A more durable traffic signal with metal poles that have signal lights instead of lights connected to wooden poles.
- Traffic cameras to monitor and adjust the signal in real-time, as well as vehicle detection in the pavement so the signal can recognize when a person driving is waiting at the light.
- New sidewalks and upgraded ADA accessible concrete curb ramps and curb bulbs at all four corners of the intersection.
- Permanent crosswalks at each crossing.
Public Art Installation
On November 9, 2023 this 17-foot-tall Steller’s jay landed on southwest corner of Highland Park Way SW and SW Holden St, welcoming all to the neighborhood. This new public artwork was created by Matthew Mazzotta and is titled Where’s the Party: Elevating Nature and Resilience. It was chosen by a community selection panel and administered by Seattle Office of Arts & Culture as part of the Highland Park Way SW and SW Holden St Safety Improvements Project.

Project History & Additional Traffic Calming
The closure of the West Seattle Bridge on March 23, 2020 brought significant traffic to the Highland Park neighborhood and to the already-strained intersection of Highland Park Way SW and SW Holden St. One of the first projects we built shortly after the bridge closed was a temporary signal at the intersection. This temporary signal will be replaced by a permanent signal as part of the Highland Park Way SW and SW Holden St Safety Improvements project.
In June and July 2020, we also built speed humps and cushions in nine locations near the intersection to support safety around the new traffic signal. These locations are shown below. The speed humps and cushions help slow down vehicles as they approach the intersection and discourage neighborhood cut-through traffic. Speed humps are a solid hump across the road and speed cushions leave spaces between for emergency vehicles and people biking to easily pass through.
Separate from this project, the Reconnect West Seattle project team added traffic calming in the Highland Park neighborhood to address detour traffic from the West Seattle Bridge closure, through a Home Zone. A Home Zone involves the entire neighborhood working together to prioritize improvements that calm traffic on residential streets and improve pedestrian mobility and neighborhood livability.
