We hit up the well known as our Gowanus archive for another Gowanus Back in the Day historic photo from the Brooklyn Public Library‘s extensive collection of historic Brooklyn pics. This is an aerial shot of the Carroll Street Bridge from the 1950s. The notes with the photo say, “Portion of Gowanus Canal showing Carroll Street and Union Street bridges; tugboats docked in canal, lower left; warehouses and industrial plants on both sides of canal, with parked trucks and automobiles; large water tower in right foreground; rows of residential buildings in left background.” The caption reads, “Carroll Street Bridge — A retractile bridge carrying Carroll Street over Gowanus Canal. Opened to traffic in 1889.”
