Council Transportation Chair Pedersen Launches Audit of Seattle Bridges

Home » Council Transportation Chair Pedersen Launches Audit of Seattle Bridges

Councilmember Alex Pedersen (District 4 – Northeast Seattle), and Chair of the Council’s Transportation Committee, today asked the City Auditor to complete an audit to assess the conditions and maintenance of Seattle’s bridges.

“In a city surrounded by several waterways, our bridges are the backbone of Seattle’s infrastructure for its residents and local economy and are vital for transit, freight, and other uses,” said Pedersen. “Bridges require relatively large investments to build and maintain to ensure they remain safe for generations. The rapid deterioration of the West Seattle Bridge underscores the need for City officials and the general public to have a clear, thorough, and independent understanding of the condition of major bridges throughout Seattle, including preventative maintenance investments and practices.”

Pedersen’s letter to the City Auditor states the purpose is “to request, as chair of the City Council’s Transportation and Utilities Committee, that the Office of City Auditor complete an audit report to assess the physical conditions and maintenance investments for the major bridges owned by the Seattle Department of Transportation (SDOT)…”

“We look forward to performing this important and valuable body of work,” said David G. Jones, the City Auditor.

“I appreciate SDOT’s recent transparency, responsiveness, and proactive sharing of information regarding the West Seattle Bridge.  I want SDOT to remain focused on the immediate needs of the West Seattle Bridge and I am therefore, flexible on the Auditor’s final completion date for reviewing the other bridges,” said Pedersen, who has also requested an interim summary of the maintenance investments on bridges by mid-September to inform the City Council’s fall budget process.

According to the City of Seattle’s adopted 2020 operating budget (page 411) and SDOT’s 2019 Capital Roadway and Structures report (page 19), there are 124 bridges owned and operated by the City of Seattle. The City Auditor’s report will focus on SDOT’s bridge maintenance program for the major bridges in the City’s portfolio and may discuss other non-bridge assets managed by SDOT.  While SDOT already obtains and monitors much of this underlying information on our City’s bridges and the federal government and state government also provide important oversight, the audit will gather, summarize, and analyze that information for review by the City Council.

For the proposed scope of the audit, use the following website link:

In addition to summarizing key information on all major bridges, the report should include a deeper analysis of a sampling of major bridges across our city including, but not limited to, the Ballard Bridge, Magnolia Bridge, Montlake Bridge, University Bridge, and West Seattle Bridge.

The Auditor will discuss the final scope with SDOT, which could include a description of other major non-bridge infrastructure assets owned by the City to provide context for SDOT’s broader asset management portfolio.
