  • The Downtown Seattle Transit Tunnel (DSTT), also referred to as the Metro Bus Tunnel, is a 1.3-mile-long (2.1 km) pair of tunnels for public transit that run north–south under 3rd Avenue through Downtown Seattle, Washington from 9th Avenue and Pike Street to 5th Avenue South and South Jackson Street. The double-track tunnel and its stations, with the exception of Convention Place, constitute parts of the Central Link light rail line, which continues north to University of Washington station and south through the Rainier Valley to Seattle–Tacoma International Airport as part of Sound Transit's Link Light Rail network. All five of its stations are also served by buses from King County Metro and Sound Transit Express that leave the tunnel north via Interstate 5, south via the SODO Busway, or east via Interstate 90. The DSTT is the busiest section of the Link Light Rail network, with an average of over 10,000 weekday boardings. It is owned by King County Metro and shared with Sound Transit, having signed a joint-operating agreement after ownership was transferred back to King County in 2002. The Downtown Seattle Transit Tunnel is one of two rail-bus tunnels in the United States, alongside the Mount Washington Transit Tunnel in Pittsburgh, Pennsylvania. However, the DSTT is the only rail-bus tunnel in the United States with stations, as the Mount Washington Transit Tunnel lacks stations. Though proposals for a rapid transit tunnel under 3rd Avenue date back to the 1910s and 1920s, planning for the modern bus and rail Metro Bus Tunnel only began in 1974. The King County Metro Council approved the bus tunnel proposal in November 1983, but construction did not begin until March 1987. The tunnel between Convention Place and Westlake stations was built using the cut-and-cover method, closing Pine Street for 19 months and disrupting nearby retail businesses. The segment from Westlake to the International District was bored with two tunnel-boring machines, heading north from Union Station and finishing within a month of each other. Tests of normal buses and the Breda dual-mode buses built specifically for tunnel routes began in March 1989, with tunnel construction declared complete in June 1990, at a cost of $455 million. Light rail tracks were installed in anticipation of future rapid transit service through the tunnel, later found to be poorly insulated and unusable for Link Light Rail. Soft openings of the five tunnel stations were held from August 1989 to September 1990, with regular bus service beginning on September 15, carrying 28,000 daily trips in its first year of operation. The tunnel was closed on September 24, 2005 for modification to accommodate both buses and Sound Transit's Central Link light rail trains on a shared alignment. Prior to closure, around two dozen bus routes ran through the tunnel. The buses were dual-powered, operating as trolleybuses in the tunnel using electricity from overhead wires and as diesel buses on city streets. It reopened on Monday, September 24, 2007. The two-year closure included retrofits for light rail and other operating system upgrades. A stub tunnel, branching from the main tunnel, was constructed under Pine Street between 7th and Boren Avenues to allow light rail trains to stop and reverse direction and for a later extension of Central Link that opened in 2016. Due to the conversion to light rail, dual-mode trolleybuses can no longer operate in the tunnel. Those buses have already been replaced by Metro's current new fleet of hybrid buses, which produce fewer emissions than standard diesel buses, and, unlike the trolleybuses, require no connection to overhead wires. Since the floor of the tunnel was lowered for the light rail, bus mirrors are now at head height, and there have been concerns that they may strike passengers waiting on the platform. To prevent this, the mirror on the platform side of the bus are equipped with flashing lights and the speed limit in stations has been lowered from 15 to 10 mph (24 to 16 km/h). (en)
  • El Downtown Seattle Transit Tunnel (DSTT), también conocido como el Metro Bus Tunnel, es un 1,3 millas (2,0921472 km) par de túneles para transporte público que funciona de norte–sur bajo la Tercera Avenida sobre el Centro de Seattle, Washington desde la Novena Avenida y Pike Street a la Quinta Avenida Sur a South Jackson Street. El túnel de doble vía y sus estaciones, con la excepción de Convention Place, constituyen la estación meridional de la Central Link del Tren Ligero de Seattle, continuando al sur por Rainier Valley al Aeropuerto Internacional de Seattle–Tacoma como parte de la red del Tren Ligero de Seattle operado por Sound Transit. Todas sus cinco estaciones son servidas por autobuses de King County Metro y Sound Transit Express que salen del túnel al norte vía la Interestatal 5, al sur vía SODO Busway, o al este vía la Interestatal 90. La DSTT es la sección más ocupada de la red del Tren Ligero de Seattle, con un promedio de 10,000 pasajeros al día. Es propiedad de King County Metro y compartido con Sound Transit, al haber hecho un acuerdo en conjunto para operar, cuando el condado de King tomo cargo en 2002. El Downtown Seattle Transit Tunnel es uno de dos túneles de autobuses y trenes en los Estados Unidos, junto con el Mount Washington Transit Tunnel en Pittsburgh, Pensilvania, pero sin ninguna estación.

  • Il Downtown Seattle Transit Tunnel', o Metro Bus Tunnel, è un tunnel di transito di 1,3 km che si trova sotto Downtown Seattle, dalla 9th Avenue e Pike Street fino a 5th Avenue S. e S. Jackson Street. Approvato dal Metro Transit nel 1983, la costruzione iniziò nel 1987. Venne completata ed entrò in esercizio nel 1990 per un costo totale di $455 milioni Nel maggio del 2000 il consiglio comunale trasferì la proprietà alla Sound Transit ma la proprietà venne ritrasferita nuovamente alla King County Metro nel 2002. Il tunnel venne chiuso il 24 settembre del 2005 per permettere l'utilizzo congiuto della linea della metropolitana leggera Central Link e degli autobus. Prima della chiusura il tunnel era utilizzato da circa dodici linea d'autobus. GLi autobus erano a doppia alimentazione, usavano l'elettricità all'interno del tunnel (come i filobus) e il diesel nelle strade cittadine. Il tunnel venne riaperto il 24 settembre del 2007. Inoltre, venne costruito un tunnel minore, proveniente dal tunnel principale, sotto Pine Street tra 7th e Boren Avenues per permettere ai treni di fermarsi ed invertire il senso di marcia e per future estensioni del Central Link. A causa della conversione per il Central Link, i filobus non possono più accedere al tunnel. Questi autobus sono già stati sostituiti dalla nuova flotta di veicoli ibridi del King County Metro. Mentre quegli autobus producevano molte più emissioni rispetto ai filobus standard, i nuovi producono molte meno emissioni rispetto agli standard autobus diesel e non hanno bisogno di una connessione per la rete elettrica. Da quando il pavimento del tunnel è stato abbassato per la ferrovia leggera sono nate delle preoccupazioni sul fatto che gli specchietti degli autobus si trovino all'altezza della testa delle persone e potrebbero colpire quelli in attesa nelle piattaforme. Per evitare questo gli specchi sono stati dotati di luci intermittenti. Allo stesso tempo la velocità di ingresso e di uscita dalle stazioni è stata abbassata da 24 km/h a 16 km/h. Il tunnel è interamente nell'area Ride free (dove non vi è bisogno di pagare il biglietto), quindi nessun costo hanno gli autobus in nessuna delle cinque fermate durante le ore in cui è attivo il servizio gratuito. A causa della differente politica della Sound Transit, è richiesto il biglietto sul Central Link. (it)
