By the 1830s, inspired by the Erie Canal, Alderman Daniel Richards built the Atlantic Basin at Red Hook, which was followed by the Erie Basin. This was a massive success in terms of industrial activity and the home to the first grain elevator in the burgeoning Port of New York. At the time, 80% of grain in the state traveled through Brooklyn. By 1869, the Gowanus Canal — a project through which the natural Gowanus Creek was widened and adjacent swampland was dredged for factories and warehouses — was complete, and 700 buildings were constructed here per year for the next decade.

The current Hamilton Avenue Bridge, seen in the far distance in this image, was built in 1942 and, like the Union and 3rd Street bridge, is a vascular bridge (where two leaves lift up to allow marine traffic through). Today the Brooklyn-Queens Expressway also towers over the Hamilton Avenue Bridge.
