The South Park Bridge (also called the 14th/16th Avenue South Bridge) is a Scherzer Rolling Lift double-leaf bascule bridge in Seattle, Washington, United States, constructed in 1929–31. It carries automobile traffic over the Duwamish River[3] near Boeing Field, just outside the city limits of Seattle. It was named for the nearby South Park neighborhood of Seattle. It was listed on the National Register of Historic Places in 1982, as the 14th Avenue South Bridge. Due to safety concerns, the bridge was closed to traffic on June 30, 2010, and its bascule draw-span leaves were removed in August 2010, while county officials worked to secure funds for replacement of the draw span. Work to replace the bridge began in May 2011, and the bridge reopened to traffic on June 30, 2014, ending a four-year closure.

Replacement

The bridge is operated by the King County government. Prior to its 2010 closure for rebuilding, about 20,000 vehicles used the bridge daily, and it was a main connection to South Park's main business district.[4]

The bridge was already in poor condition in 2001, when it was further damaged by the Nisqually earthquake. In 2002, King County inspectors gave the bridge a score of 6 out of a possible 100, per Federal Highway Administration criteria, and the rating later fell to as low as 4.[5][6] This compares to a score of 50 for the I-35W Mississippi River bridge, which collapsed in August 2007.

Due to lack of county, state and federal funding for a proposed replacement project, the South Park Bridge closed on June 30, 2010, at 7:00 p.m.[7] Although plans to build a new bridge were ready, the project did not receive a $99 million federal TIGER I grant in early 2010.[8] However, in the same month that the bridge closed, King County secured $10 million toward the replacement of bridge,[9] and in August 2010, the County submitted a grant application for $36.2 million in federal funds from the second round of federal Transportation Investment Generating Economic Recovery (TIGER II) grants.[10] Dismantling of the bridge began in late August 2010, with removal of the lift span sections,[11] and the outlook for the proposed replacement project remained unclear.

On October 15, 2010, it was announced that the South Park Bridge had been awarded $34 million in TIGER II financing, filling the funding gap and allowing work to replace the bridge to move forward.[12]

The rebuilding project began in May 2011.[13][14]

The newly completed South Park Bridge officially opened to traffic on June 30, 2014. A ceremonial grand opening event took place on June 29, 2014.[15]
