Fairview Avenue North Bridge Replacement

Thank you for attending the Fairview Avenue North Bridge Replacement Project Open House on November 10!

We discussed the new bridge design, draft detour routes, and proposed improvements. You can view the open house displays here.

Project overview

The Seattle Department of Transportation (SDOT) is committed to maintaining safety for all users of Fairview Ave N. The current bridge, built more than 65 years ago, needs to be replaced. The timber-supported bridge is structurally deficient and seismically vulnerable. Located on the southeast shore of Lake Union near the 1200 block of Fairview Ave N in Seattle, the bridge is next to the historic Lake Union Steam Plant building.


Proposed features

The new roadway configuration will better accommodate all users along Fairview Ave N.

Project improvements will include:

  • New single-span bridge structure that meets current seismic standards
  • Wider travel lanes
  • Wider sidewalks to protect pedestrians
  • Structurally able to accommodate future transit expansion
  • New lookout points along the bridge
  • Improved pedestrian lighting, landscaping, wayfinding


Full bridge closure

Originally, we aimed to keep the bridge open to traffic throughout construction. However, due to the complexity of the project, and in order to shorten the total construction time and reduce costs, we have decided that the most prudent approach is to close the entire bridge for the full project construction duration of approximately 15 months. We are committed to using taxpayer dollars efficiently and shorten the length of construction projects whenever possible. We are conducting a traffic analysis, coordinating with King County Metro and facilitating a parking study as part of our planning for a full bridge closure.

Project schedule

*The project will comply with all necessary environmental permitting and associated schedules
**Construction start date pending permit approval

Project Budget and Funding

The total project estimate is $42 million and the project is fully funded in three ways: Bridging the Gap, a nine-year levy for transportation maintenance and improvement, and federal funding through the Bridge Replacement Advisory Committee (BRAC), and funds from the recently passed Move Seattle levy.
