The Green Line Extension (sometimes abbreviated as GLX) is an initiative to expand transit services in Greater Boston by extending the Massachusetts Bay Transportation Authority (MBTA) Green Line light rail beyond its current northern terminus at Lechmere Station in Cambridge, Massachusetts. The extension is intended in order to improve mobility and regional access for residents in the densely populated municipalities of Somerville and Medford, two cities currently underserved by the MBTA relative to their population densities, commercial importance, and proximity to Boston. The project would provide Green Line service beyond a relocated Lechmere Station to College Avenue in Medford and to Union Square in Somerville using a two-branch operation, both to be operated within existing MBTA Commuter Rail rights-of-way. The extension is projected to have a total weekday ridership of about 52,000. The Green Line would see an increase in boardings of 30,700, and the MBTA system would see between 7,000 and 8,000 new transit users.〔 While on the drawing board since 1990, the project has proceeded in fits and starts. Construction finally broke ground on Phase 1 of the Green Line Extension in 2012, with service targeted to begin in 2020.〔http://www.wbur.org/2014/09/13/green-line-extension-cost-rises-to-2-billion〕 ==Route== The Green Line Extension is planned to have two branches, which will split just past a relocated Lechmere station in East Cambridge. The project’s two branches consist of: * A main branch, long, to Medford within the existing Lowell Line commuter rail right-of-way with five stations and the terminus at College Avenue in Medford. The “Medford Branch” will become part of the "D" Branch, with intermediate stations located at Washington Street, Gilman Square, Lowell Street, and Ball Square. * A second branch, approximately long, to Union Square in Somerville. This branch would follow the existing Fitchburg Line commuter rail right-of-way and includes a single station at Union Square. The Union Square Branch will be designated as part of the "E" Branch.〔〔 Additionally, the project will include acquisition of 24 new Green Line cars and construction of a support facility for storage and servicing of the fleet and existing north side Green Line operations. The original plans called for a further station, Route 16, at the Mystic Valley Parkway in West Medford, as well as an intermediate stop at Winthrop Street and Boston Avenue at the northern edge of the Tufts campus. The Winthrop Street stop was dropped from plans due to the proximity of other stations and neighborhood opposition, while the Route 16 station was placed on hold due to cost issues. In 2011, the Boston MPO decided to allocate funding in the 2016–2020 time period for the Route 16 station.〔http://www.somervillestep.org/2011/06/green_line_rout.html〕〔http://www.ctps.org/Drupal/data/pdf/plans/LRTP/paths/2035_LRTP_Amendment_Three_072214.pdf〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Green Line Extension」の詳細全文を読む スポンサード リンク
