Yesler Bridge Rehabilitation Project
Revised: November 2, 2015
Starting the week of Oct. 19, Seattle City Light (SCL) will be working 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 needs to occur before the SDOT can rehabilitate the Yesler Way Bridge. 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.
For more information and a map of this work, please visit SCL's project website.
Before construction can begin on the bridge, SDOT needs to complete an additional review and evaluation of the project design and construction. This will be specific to Section 4(f) of the Federal Transportation Act, which requires transportation agencies to minimize harm to historic properties. This evaluation will demonstrate how the current design alternative to rehabilitate the bridge and preserve its key, historic character-defining features minimizes harm to the character of Pioneer Square and surrounding historic buildings wherever possible.
SDOT does not anticipate that this additional review will lead to changes in the design for the rehabilitation of the bridge.
This additional review moves the anticipated start of construction to spring 2016 rather than December 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 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.
Improvements to the bridge include:
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.
Street closures during construction include:
Vehicle and transit impacts during construction include:
Vehicle and sidewalk closures:
Transit detour routes:
Vehicle detour routes:
Parking impacts during and after construction include:
Parking impacts during construction:
Parking impacts after construction:
Bridge design is nearly complete. The project team anticipates construction to begin in spring 2016 and will last for approximately 14 to 16 months.
October 2014: 60% Design
SDOT is committed to engaging with the community and understanding their needs in the project area. The outreach team will continue sharing information with stakeholders and the public in order to prepare for construction. As one of the oldest steel bridges in the city, historic preservation is an important part of the bridge’s rehabilitation. SDOT will continue working 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, setting and that impacts from construction are minimized.
PROJECT BUDGET AND FUNDING
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.
