West Seattle Bridge


The high-level West Seattle Bridge, officially the Jeanette Williams Memorial Bridge, is a cantilevered segmental bridge that serves as the primary connection between West Seattle and the rest of the city. It was built between 1981 and 1984 after the previous bascule bridge was deemed inoperable as a result of being struck by the freighter Antonio Chavez in 1978.
The bridge spans the east and west channels that form the mouth of the Duwamish River at Elliott Bay, crossing over Harbor Island. Its main approaches are Fauntleroy Way S.W. from the west and the Spokane Street Viaduct from the east. The viaduct continues east to Interstate 5 at Columbian Way, forming a three-mile arterial between West Seattle and I-5. The navigational clearance height of the high-level West Seattle Bridge is 140 feet.
The low-level Spokane Street Bridge of swing-span design spans the west channel of the Duwamish River immediately north of the high-level bridge. The low-level bridge carries the surface-level Spokane Street and has a navigational clearance of 45 feet.
The bridge was closed in March 2020 after cracks in the underside were found to be growing rapidly, necessitating a major repair amid the coronavirus pandemic. SDOT has since announced that the bridge will remain closed until at least 2022.

History

Before any permanent bridge was built along the line of Spokane Street, there had been three temporary bridges, built c. 1900, c. 1910, and c. 1918. The first one was basically a swinging gate in what had been primarily built as a water main; the second was a swing bridge that also carried a water main, and the third was a swing bridge after the water main had been rerouted elsewhere.
The original bridge was a low-level bascule bridge constructed in 1924. By the 1970s, it was one of Seattle's worst bottlenecks, due to the large number of ships in Duwamish Waterway and the frequent bridge openings. City leaders began planning a higher bridge, without a drawbridge, in the 1960s.

Replacement bridge project

Planning for the bridge was hampered by difficulties in receiving funding. In large part, this is because the bridge was not a designated highway. A 1968 Forward Thrust ballot measure included $16.7 million in funding for the bridge, largely to receive votes from West Seattle residents. Other funding sources included a state program for funding urban streets and money from a maintenance fund.
After a long drawn-out process, three companies eventually bid to design the bridge for $1.5 million. However, the city engineer chose a fourth company that was financially connected to the speaker of the state house. The price from this fourth company was triple the cost of the other three. This was a result of a series of bribes involving the head of the House Transportation Committee, the city engineer and others. Despite the 68 percent support in the 1968 ballot measure, the state withdrew its urban streets money due to the scandal. In 1976 and 1977, the conspirators were placed on trial and imprisoned.
After the scandal, the project was considered dead. Norbert Tiemann, a federal highway regulator, stated that there would essentially be no chance of the project receiving federal funds for completion. Tiemann also quipped, "Short of a tug knocking it down, there is nothing else. And you certainly wouldn't want to go that route." In March 1978, several prominent West Seattle residents filed a petition to organize a secession referendum, with the hopes of finding state funding for a new bridge to serve their independent city. The secession campaign was required to gather 29,000 signatures for a ballot measure, but were unable to meet the threshold before the drawbridges were permanently closed two months later.
On June 11, 1978, a ship struck the old bridge, which left it open and unrepairable. Because of this, the project qualified for funds from the federal Office of Special Bridge Replacement. However, with many other damaged bridges to replace, this program alone did not have sufficient funding. While federal lawmakers were opposed to appropriating funds to a high-level bridge, Seattle City Council member Jeanette Williams, who served on the council from 1970 to 1989, lobbied Congress for the bridge and successfully secured funds with help from Senator Warren Magnuson. The bridge was complete in 1984, and the smaller Spokane Street Bridge which parallels it was built at the same time.
Before the bridge opened, many of the neighborhoods in West Seattle had low property values because of the difficulty in getting downtown. The bridge caused an increase in property values as well as a development boom, as developers constructed new multi-family housing. This new development also led to an increase in traffic volumes throughout the neighborhood.

Later events

A monorail extension to West Seattle in the early 2000s was planned to use the West Seattle Bridge, with elevated columns over the center barrier. The plan was later scaled down to a single-track guideway over the bridge and abandoned entirely in 2005 over cost concerns.
On March 23, 2020, SDOT began a long-term closure of the bridge for emergency repairs after cracks in the deck were discovered during a routine inspection. The girder wall cracks had grown to within a month, while the hollow girder cracks had been noticed during inspections. An earlier report from 2014 speculated that earlier cracks had been caused by the 2001 Nisqually earthquake. On April 15, SDOT announced that the bridge will be closed until at least 2022 because of more extensive damage found and estimated time to complete bracing for the repair project.

West Seattle Freeway

The Spokane Street Viaduct section was one of Seattle's first freeways, built in 1940. Upon completion of the West Seattle Bridge in 1984, the road comprising the Spokane Street Viaduct and the West Seattle Bridge was referred to as the "West Seattle Freeway". However, a series of fatalities led to recognition that the aging Spokane Street Viaduct portion was unsafe to be used as a high-speed roadway. In 1997, the Seattle City Council unanimously adopted a resolution to lower the speed limit and to request that the WSDOT remove the word "Freeway" from signs marking the entrances to the Spokane Street Viaduct and the West Seattle Bridge. The West Seattle Bridge was renamed as the Jeanette Williams Memorial Bridge on July 6, 2009, in honor of councilmember Williams, who had been instrumental in securing political support for the construction of the bridge. However, all directional signs continue to carry the name "West Seattle Bridge."
From 2008 to 2013, the Spokane Street Viaduct section between Interstate 5 and State Route 99 was rebuilt and widened. The widened roadway has three lanes in each direction and shoulders. A new westbound on and off ramp was built at 1st Ave S and replaced the dangerous 4th Ave S off-ramp. A new eastbound off-ramp to 4th Ave S opened August 16, 2010.
