A vital connection

Spanning the Duwamish Waterway in King County, Washington the nationally significant South Park Bridge serves as a connection for freight heavy routes between the Port of Seattle, Union Pacific rail yards, King County International Airport (Boeing Field) and Seattle Tacoma International Airport. It provides one of only two crossings in the industrial area between Seattle and southern cities. Located within Washington’s 7th Congressional District, South Park serves heavily traveled, urban arterials and provides an alternative route to the 1st Avenue South Bridge—one of the region’s most freight-heavy corridors carrying over 10 million tons of freight per year.

The South Park Bridge was closed on June 30, 2010. Structurally, the bridge was deteriorating at such a rapid rate that it was no longer safe to operate. Demolition of the bridge began in August, 2010.

King County has secured $100 million in funding pledges from regional partners to build a new South Park Bridge. In August the County applied for a U.S. Department of Transportation TIGER II grant, seeking the final $36.2 million needed to fully fund the replacement bridge.

Update: On Oct. 15, 2010 King County learned it had secured a $34 million TIGER II grant, which completes financing for a new South Park Bridge.
