Built 1987. Project Description: The architectural image of this station recalls the grandeur and spaciousness of railroad stations of the past. A skylit concourse functions as the major organizing element, linking two entrances. The roof structure over the concourse is constructed of wooden arches, which rest on concrete haunches on the side walls, and support vertical posts to make the transition to flat roof. The columns supporting the concrete wall of the concourse are clad in bands of colored brick to a height of eight feet. Brick masonry is used extensively throughout the structure, particularly in the site-related construction, to respond in a sensitive manner to the context of the neighboring historical district. Project cost: $17.5 million. Project History: This station is actually three stations in one. It serves as one of the Orange Line rapid transit stations, it is an Amtrack stop, and it serves several Boston suburb commuter lines. It was one of a number of stations which were built as part of a massive Orange Line expansion program. The Orange Line is 4.7 miles of sunken transitway surmounted by 52-acres of park and punctuated by eight new stations. This entire project has been 16 years in the making. The Back Bay station is centrally located close to Copley Square. Sponsor/Developer: Massachusetts Bay Transportation Authority. Project Location: entrances on Dartmouth & Clarendon Streets, Boston, MA
