History


Background and early transit proposals

Public transit service within Seattle began in 1884, with the introduction of the city's first horse-drawn
streetcar A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are ...

across modern-day Seattle. Interurban railways to Everett, Tacoma, and the Rainier Valley were established after the turn of the century, giving the region an intercity passenger rail system to feed the streetcar lines. The interurban system failed to compete with the increasing popularity of automobile travel, capped by the completion of U.S. Route 99 in the late 1920s, and was shut down. By 1941, the streetcars had also been acquired by the municipal government and replaced with a trolleybus network. Various proposals for a

Light rail planning

Following the failed Forward Thrust initiatives, Metro Transit was created in 1972 to oversee a countywide bus network, and plan for a future rail system. In the early 1980s, Metro Transit and the

that would be convertible from buses to light rail at a later date. The PSCOG formally endorsed a light rail plan in 1986, recommending a system be built by 2020, and include a line between Seattle and Sea-Tac Airport, with routing alternatives that served the Rainier Valley. A 1988 advisory measure on light rail planning was passed in King County, encouraging Metro Transit to accelerate the plan's timeline to open by 2000. In 1990, the state legislature endorsed the creation of a regional transit board composed of politicians from King,

The agency proposed a light rail network as the centerpiece of a $6.7 billion transit ballot measure, with a surface line through the Rainier Valley and tunnels between Downtown Seattle, Capitol Hill, and the University District. The ballot measure failed to pass on March 14, 1995, and the light rail line was shortened to , between the University District and Sea-Tac Airport. Voters approved the $3.9 billion package on November 5, 1996, along with increases to sales taxes and motor vehicle

Budget issues and delays

The Central Link project was originally planned to open in 2006 and projected to cost $1.9 billion (equivalent to $ in dollars), but the estimates were found to be unrealistic by auditors in November 2000. New executives, hired by Sound Transit to replace previous program directors, presented a revised plan with an opening date pushed back three years to 2009 and a $3.8 billion (equivalent to $ in dollars) cost estimate. Planning of the Portage Bay tunnel between Capitol Hill and the University District was suspended due to higher than expected contractor bids, attributed to difficult soil conditions. Sound Transit adopted the revised budget and schedule in January 2001, including provisions to re-study routing options between Downtown Seattle and the University District, along with a $500 million federal grant agreement to fund the construction of an "initial segment" for the project. The initial segment identified and approved by Sound Transit later that year shortened the line to , between Downtown Seattle and a southern Tukwila station near Sea-Tac Airport. The remaining routes to the airport and University District were sent back to the planning stage, and re-organized into separate light rail projects. In November 2001, Sound Transit approved construction of the shortened Central Link light rail project, calling for a summer 2002 groundbreaking. Property acquisition in the Rainier Valley began in March 2002, but two legal battles delayed the start of construction. In November 2002, the

Construction and testing

Sound Transit received its $500 million federal grant agreement in October 2003, and a groundbreaking ceremony was held in SoDo on November 8, 2003. Construction contracts for various segments were awarded in 2004 and 2005, coming six percent under Sound Transit's estimates, and work began along all parts of the system. The first rails were installed on August 18, 2005, in the SoDo area; a month later, the downtown transit tunnel closed for a two-year renovation to accommodate light rail service. Excavation of the Beacon Hill tunnel and station began in 2005, and two

The SODO and Stadium stations were completed in May 2006, and light rail testing in the SoDo area began the following March.
