Known as the Old Colony Railroad Bridge, the Scherzer design rolling lift bridge dates to 1898. With the decline of passenger rail service following the Second World War, only one of the three drawbridges remained in use. All were demolished by 1988, replaced by a fixed span across the channel. A preserved fragment of the bridge by artist Ross Miller serves as a monument in the park to the area’s industrial past. Behind the sculpture, trains enter Boston’s South Station.
