Location

Ball Square station is a light rail station on the Massachusetts Bay Transportation Authority (MBTA) Green Line located at Ball Square in Somerville and Medford, Massachusetts. The accessible station has a single island platform serving the two tracks of the Medford Branch. It opened on December 12, 2022, as part of the Green Line Extension (GLX), which added two northern branches to the Green Line, and is served by the E branch.

The location was previously served by railroad stations. The Boston and Lowell Railroad (B&L) opened Willow Bridge station at Cambridge Road (now Broadway) by 1850. It was renamed North Somerville around 1878, and a new station building was constructed in the 1880s. The station was served by the Boston and Maine Railroad, successor to the B&L, until 1958. Extensions to the Green Line were proposed throughout the 20th century, most with North Somerville as one of the intermediate stations. A Ball Square station near the former station site was officially chosen for the GLX in 2008. Cost increases triggered a wholesale reevaluation of the GLX project in 2015, and a scaled-down station design was released in 2016. A design and construction contract was issued in 2017. Construction of Magoun Square station began in early 2020 and was largely completed by late 2021.
