PROJECT UPDATES

Expect early utility relocation work to occur in April/May (3/30/2016)
During April and May, SDOT is working with utility companies to relocate utility lines ahead of starting bridge construction. This early utility work will not require any street closures or impact traffic on Yesler Way or 4th Ave.

Bus only lane extension on 5th Ave (3/18/2016)
In conjunction with the Yesler Bridge Rehabilitation Project, SDOT extended the existing 5th Ave transit contraflow lane by two blocks between Terrace and S Washington streets (green arrow on the map). The bus only lane extension was completed in February 2016. SDOT also added new parking spaces along the west side of 5th Ave between Jefferson and Terrace in March 2016.

Seattle City Light Utility Relocation (3/18/2016)
Seattle City Light (SCL) is wrapping up work to underground power lines currently on the underside of the Yesler Way Bridge over 4th Avenue that serves the 400 Yesler Way Building. This work will maintain service to the building during construction of the bridge and improve the area's overall electrical reliability by undergrounding the lines. SCL began work in October 2015. For more information and a map of this work, please visit SCL's project website.

CONSTRUCTION IMPACTS

During construction, vehicle and transit detours will be in effect and a number of parking spaces will be removed because of several street closures and channelization changes.

  • Yesler Way will be closed in both directions between 3rd Ave and midway between 5th Ave and 6th Ave
  • Terrace St will be closed to through traffic, open to local access
  • 4th Ave will have ongoing lane closures and occasional full nighttime and weekend closures

PROJECT OVERVIEW

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, starting as soon as May 2016 and lasting through fall 2017.

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 providing a major east/west arterial connection across I-5, the bridge displays unique and historic design elements which include decorative pedestrian railings, parabolic and circular features of the exterior “fascia” girders, and ornamental capitals and casings on the “fascia” girder columns, all of which will be preserved with the bridge rehabilitation.

IMPROVEMENTS

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 curb ramps that meet Americans with Disabilities Act (ADA) standards to the maximum extent feasible at crosswalk locations within the project limits
