When the West Seattle High-Rise Bridge (high bridge) closed on March 23, 2020, we also had to restrict access to the Spokane St Swing Bridge (low bridge). Daytime access to the low bridge was restricted to ensure that freight, transit, and emergency response vehicles can travel efficiently to and from West Seattle.

With public safety as our top priority, the low bridge access was restricted to keep the low bridge clear for emergency vehicles, transit, and heavy freight. Read the full low bridge access policy here (no longer an active policy as of September 17, 2022).         

Policy Goals and objectives

When automated enforcement on the low bridge began in early 2021, we monitored traffic volumes on the low bridge and we took a hard look at the low bridge access policy, identified goals and objectives, and adjusted the policy as circumstances change. 

Objectives throughout the West Seattle Bridge closure 

Health, life, and safety objectives:

  • Ensure reliable travel time for emergency vehicles at all times of day
  • Prioritize trips that improve patient and provider access to lifesaving medical treatment

Mobility and system operations objectives:

  • Maintain Spokane Street corridor performance throughout the day, including a 1 to 1 recovery time following a bridge opening or incident
  • Prioritize public transit, high-capacity modes, and high-occupancy vehicles
  • Reduce single-occupant travel and detour route congestion

Economic growth and sustainability objectives:

  • Prioritize freight movement to support economic health and decrease detour route traffic
  • Support businesses with critical and urgent needs including businesses impacted by COVID-19

Automated Photo Enforcement

Automated enforcement on the low bridge allowed us to better enforce the low bridge access policy. The automated enforcement system used photographs of license plates to identify unauthorized low bridge users. SPD officers reviewed each violation photo, which is required by State law. Violation photos were taken of the vehicle to capture the license plate number, not the person driving, and are prohibited from being used for any other law enforcement action. There is a $75 cap on citations, along with Seattle Municipal Court's community service in lieu of fee and zero-interest payment plans, to prevent citations from causing financial hardship to low-income individuals.
