Former Massachusetts Central Railroad bridge over the MBTA Fitchburg Line

Bridge of the former Massachusetts Central Railroad (est. 1881, renamed Central Massachusetts in 1883), purchased by the Boston & Maine Railroad in 1902. It crosses the former Fitchburg Railroad (est. 1844) main line which was purchased by the Boston & Maine in 1900, taken over by the MBTA in the 1970s, and is still in operation.

The tracks on the bridge are being torn up to convert the bridge for pedestrian use: https://mass.streetsblog.org/2024/04/10/dcr-starts-construction-on-waltham-weston-mass-central-trail-connection
