The Carroll Street Bridge over the Gowanus Canal is 120 years old. It’s a retractile bridge, one of only four in the U.S.; to open, the bridge rolls back on steel rails. Fortunately, this is pretty far up the canal and doesn’t have to allow boats through often. This picture is of the gate that swings shut to prevent cars from crossing when the bridge is moving. With the cobblestones and brick buildings, the scene is olde timey, except for the Bkln Yard visitors to the right.
