East Somerville station is an under-construction light rail station on the Massachusetts Bay Transportation Authority (MBTA) Green Line located in southeastern Somerville, Massachusetts. The accessible station has a single island platform serving the two tracks of the Medford Branch, which parallels the Lowell Line. It is planned to open in mid-2022 as part of the Green Line Extension (GLX) and will be served by the E branch. The Boston and Lowell Railroad (B&L) opened a station at Milk Row in 1835; it was replaced with Prospect Hill station in the 1880s. The station was served by the Boston and Maine Railroad, successor to the B&L, until 1927. Extensions to the Green Line were proposed throughout the 20th century, most with Washington Street as one of the intermediate stations. A separate station in the Brickbottom neighborhood was rejected in 2008, though the planned station at Washington Street was renamed Brickbottom by 2011. The MBTA agreed in 2012 to open the station by 2017, and a construction contract was awarded in 2013. Cost increases triggered a wholesale reevaluation of the GLX project in 2015. A scaled-down station design was released in 2016, with the station renamed to East Somerville later than year. A design and construction contract was issued in 2017. Construction of East Somerville station began in early 2020 and was largely completed by late 2021.
