Project Overview

Earthquakes could have a significant detrimental effect on Seattle's infrastructure. To address seismic risks to city infrastructure, the City of Seattle established a bridge seismic retrofit program to assess the seismic vulnerability of the City's bridges and to prioritize limited funding to reduce this transportation infrastructure vulnerability.

The Levy to Move Seattle funds our bridge seismic retrofit program. We have already completed seismic retrofits on 4 bridges with Levy dollars since 2016!

Located just north of the Ballard Bridge, the Leary Way Bridge carries traffic over NW Leary Way, via 15th Ave NW.

The Leary Way Bridge project includes several modifications to strengthen the existing bridge, beyond typical maintenance, and make the bridge less vulnerable in the event of an earthquake.

  • Strengthening the bridge's cap beams, columns, footings, and abutments (parts of the bridge structure)
  • Installing ground anchors 
  • Repairing cracks and damaged concrete 
  • Replacing the bridge expansion joints

The total project estimate is $4.7 million, and the project is funded through the Levy to Move Seattle and a federal grant. Approved by voters in 2015, the 9-year, $930 million Levy to Move Seattle provides funding to improve safety for all travelers, maintain our streets and bridges, and invest in reliable, affordable travel options for a growing city.
