Yesler Bridge Rehabilitation Project

Revised: May 20, 2015


The Seattle Department of Transportation (SDOT) will be rehabilitating the Yesler Way Bridge, located at the intersection of Yesler Way and Terrace St over 4th Ave S.

Built in 1910, the bridge is one of the oldest permanent steel roadway bridges in the City of Seattle. SDOT will be rehabilitating the Yesler Way Bridge to improve safety and reliability while preserving the bridge’s historical elements.

The Yesler Way Bridge is vital in connecting residents, commuters, workers and businesses in the surrounding area and neighborhoods. In addition to being a major connector, the bridge displays unique and historic design elements which include decorative pedestrian railings, ornamental capitals, casings, and corbels on the exterior “fascia” girders.


Improvements to the bridge include:

  • Remove interior steel columns to form a single span superstructure
  • Rehabilitate east abutment wall and replace west abutment wall
  • Reconstruct the northwest staircase
  • Rehabilitate and preserve the key historic features of the bridge, which include:
    • North and south fascia girders, columns, cladding, capitals and corbels
    • North and south pedestrian railings
    • Decorative lighting on north fascia girder
  • Improve intersection design to reduce crosswalk distance, accommodate ADA and increase user safety
  • Provide Americans with Disabilities Act (ADA) compliant curb ramps at crosswalk locations within the project area, where feasible


Bridge design is nearly complete. The project team anticipates construction to begin in late 2015 and last for approximately 14 to 16 months.

October 2014: 60% Design
April 2015: 90% Design
September 2015: Final Design
December 2015: Begin Construction
Spring 2017: Project Complete


SDOT is committed to engaging with the community and understanding their needs in the project area. The project team will host briefings, informal drop-in sessions and open houses at various stages throughout design and construction to engage interested and affected stakeholders.

As one of the oldest steel bridges in the city, historic preservation is an important part of the bridge’s rehabilitation. The outreach team has worked closely with the Pioneer Square Historic Preservation Board and International Special Review District Board to ensure the bridge and nearby neighborhoods maintain their key historic features and setting.

The project budget is approximately $16.1 million. Funding for the project comes from the Bridging the Gap (BTG) transportation levy, passed by voters in November 2006, and a grant from the Federal Highway Bridge Program.
