Fairview Avenue North Bridge Replacement

Project overview

The Seattle Department of Transportation is committed to maintaining safety for all users of Fairview Avenue North. The current bridge was built 65 years ago and needs to be replaced. While safe for travel today, the bridge is structurally deficient and seismically vulnerable. Located on the southeast shore of Lake Union near the 1200 block of Fairview Avenue North in Seattle, the bridge is adjacent to the historic Lake Union Steam Plant building, which is occupied by ZymoGenetics.

Proposed features

The new roadway configuration will better accommodate all users making it safer for people to drive, walk, bike, and access transit along Fairview Avenue North.

Project improvements will include:

  • Increased structure width to allow for wider vehicle travel lanes
  • Pedestrians buffered from moving traffic by additional sidewalk width
  • Structurally able to accommodate future transit expansion
  • Improved pedestrian lighting, landscaping, wayfinding

Project Budget and Funding

The total project estimate is $48 million.  The project is fully funded through the design phase. Additional funds are needed for construction. Existing funds are generated from Bridging the Gap, a nine-year levy for transportation maintenance and improvement, and federal highway bridge funding through the Bridge Replacement Advisory Committee (BRAC).  SDOT is working to close the existing funding gap.       

Bridging the Gap is a $365 million levy that was passed by Seattle voters in November 2006. The goal of the program is to create a strong foundation for Seattle’s transportation future by reducing the infrastructure backlog and investing in major transportation projects.

BRAC provides advice to help inform selection of bridge replacements or rehabilitation of bridges owned by cities or counties.
