The new bascule bridge opened to traffic June 30, 2014, and is notable for several reasons: • It is designed to a 975-year seismic event with innovative solutions that bid within 10 percent of the engineer’s estimate. • It was constructed on an Environmental Protection Agency-designated “Superfund” site, requiring extensive environmental permitting. • The project was construction-sequenced to accommodate annual 6.5-month-long in-water work periods (fish windows) while meeting the Muckleshoot Tribe’s fishing needs. • At the public’s request, the bridge architecturally emulates and preserves aspects of the original, historic bridge. Closing a vital, beloved bridge The original South Park Bridge, built in 1931, was a Old Bridge (1929-2010) double-leaf bascule bridge listed on the National Historic Register and designated as a King County Landmark. The 1,045-foot-long bridge, popular with the local residents for its look and importance to the community, connected Seattle neighborhoods across the Duwamish Waterway, a navigable channel used for commercial, industrial and recreational purposes. The bridge had suffered over the years and was rapidly deteriorating. Further, it was seismically vulnerable for two main reasons: 1. The original foundation piles were not driven completely through a deep layer of liquefiable soil 1 | Page South Park Bascule Bridge Replacement 2015 APWA Washington Project of the Year Nomination Transportation, More than $75 million into the solid glacial till below. 2. The concrete structure was weakened by cumulative damage from previous earthquakes. The tilting and cracking of the main piers meant the bridge was susceptible to reactive movement as the bascule spans opened and closed. The bridge required extensive maintenance and operations to maintain alignment of the moveable spans and machinery. In May 2008, King County Department of Transportation launched the ambitious South Park Bascule Bridge Replacement Project, selecting HNTB as the final design consultant. The team overcame numerous challenges, including: “This bridge is critical to several • Permitting for construction in a “Superfund” site neighborhoods: It is critical to • Meeting unprecedented seismic performance South Park, and to Georgetown, • Historic preservation criteria and to the industrial area of • Continually informing the community to generate patience Seattle.” during a long funding pursuit and a lengthy construction phase — Dagmar Cronn, South Park • Achieving a design that enhances maintainability and community leader reliability Ultimately, the bridge was classified structurally deficient and functionally obsolete, receiving a startling sufficiency rating of four out of 100. Without funding for a replacement, the King County DOT closed the bridge on June 30, 2010, due to safety concerns. Replacing the South Park Bridge was a top priority for King County Executive Dow Constantine. He led the charge, securing necessary local and federal funding by October of that same year. “I hereby pledge to do all within my capacity to secure funding for the replacement of the South Park Bridge,” Constantine said.

It opened to traffic on June 30, 2014. The notable features of the project include: • Provides a reliable link to South Park neighborhood businesses that rely on the bridge for economic benefit. • Preserves potential economic development upriver with a bridge that provides unlimited vertical navigation clearances instead of a fixed-span crossing. • Provides capacity and redundancy to the local roadway network, especially to heavy truck volumes, which carry approximately 10 million tons of freight annually across the bridge, including aerospace parts to local Boeing facilities. • Provides a beautiful landmark bridge with art and other aesthetic features and an adjacent park to restore pride and promote new development in the beleaguered South Park community.
