The Alaskan Way Viaduct ("the viaduct" for short) was an elevated freeway in Seattle, Washington, United States, that carried a section of State Route 99 (SR 99). The double-decked freeway ran north–south along the city's waterfront for 2.2 miles (3.5 km), east of Alaskan Way and Elliott Bay, and traveled between the West Seattle Freeway in SoDo and the Battery Street Tunnel in Belltown.

  • The Alaskan Way Viaduct ("the viaduct" for short) was an elevated freeway in Seattle, Washington, United States, that carried a section of State Route 99 (SR 99). The double-decked freeway ran north–south along the city's waterfront for 2.2 miles (3.5 km), east of Alaskan Way and Elliott Bay, and traveled between the West Seattle Freeway in SoDo and the Battery Street Tunnel in Belltown. The viaduct was built in three phases from 1949 through 1959, with the first section opening on April 4, 1953. It was the smaller of the two major north–south traffic corridors through Seattle (the other being Interstate 5), carrying up to 91,000 vehicles per day in 2016. The viaduct ran above Alaskan Way, a surface street, from S. Nevada Street in the south to the entrance of Belltown's Battery Street Tunnel in the north, following previously existing railroad lines. The viaduct had long been viewed as a barrier between downtown and the city's waterfront, with proposals to replace it as early as the 1960s. Questions of the structure's seismic vulnerability were raised after several earthquakes damaged similar freeways in other cities, including some with the same design as the viaduct. During the 2001 Nisqually earthquake, the Alaskan Way Viaduct suffered minor damage but later inspections found it to be vulnerable to total collapse in the event of another major earthquake, necessitating its replacement. The state and city governments considered several options, including a rebuilt elevated structure, a surface boulevard, and cut-and-cover tunnel, but could not compromise on a final choice. A deep-bored tunnel was selected in 2009 and the southern section of the viaduct was demolished in 2011 and replaced with a six-lane, single-deck freeway that travels through the SoDo industrial area. Excavation of the downtown bored tunnel by the tunnel boring machine "Bertha" began in 2013 and was completed in 2017 after two years of delays. The viaduct was closed permanently on January 11, 2019, and the new tunnel opened three weeks later on February 4. Demolition of the viaduct began weeks later, and was complete by late 2019. (en)
  • La Alaskan Way Viaduct (Viadukto Alaskan Way aŭ Viadukto super Vojo Alaska) estis duetaĝa levita aŭtovojo en Seatlo, Vaŝingtonio, Usono, kiu portis sekcion de Ŝtata Ŝoseo 99 (SR 99). La aŭtovojo direktiĝas norden-suden laŭ la havena marbordo distancon de 3,54 km, oriente de Alaskan Way kaj Golfeto Elliott, kondukante aŭtojn inter la Aŭtovojo al Okcidenta Seatlo en SoDo kaj la Tunelo sub strato Battery en Belltown. La viadukto konstruiĝis en tri fazoj de 1949 ĝis 1959. La unua parto malfermiĝis la 4-an de aprilo 1953. La viadukto estis la malpligranda el la du gravaj nord-sudaj trafikaj koridoroj tra Seatlo (la alia estas InterŜtata Ŝoseo 5). En 2016 ĝi portis ĝis 91,000 veturilojn tage en 2016. Pro timoj pri ĝia frakasebleco en tertremo, la registaro ekde la 1960-aj jaroj proponis forigi la viadukton, des pli post la tertremo Nisqually en 2001, kiu faris al ĝi iomete da damaĝo. Postaj sismologiaj taksoj indikis, ke plua tertremado povus kolapsigi ĝin. La ŝtata kaj urba registaroj konsideris plurajn eblojn, inkluzive de rekonstruita strukturo, surfaca stratego kaj tranĉita-kovrita tunelo, sed ne povis kompromiti al fina elekto. Finfine en 2009 oni decidis bori profundan tunelon sub la urbocentro. En 2011 oni malkonstruis la sudan parton de la viadukto, kaj en 2019 oni intencas forigi la ceteran, pli nordan parton, malfermante al trafiko la tunelon en februaro 2019. La fermiĝo efektiviĝis en la vespero de la 11-a de januaro, 2019. La 22-an de novembro finiĝis la malkonstruado. (eo)
