In the Brooklyn neighborhood of Sheepshead Bay, one grid-defiant road runs askew to the grid, connecting Gravesend Neck Road to the bay. Its route follows an obscure stream that used to cause flooding in the area.
As seen in this 1933 photo from the NYPL Digital Collections, a heavy downpour brought Squan Creek back to the surface. Above is the intersection of East 11th Street and Avenue Y where the creek’s course flowed until the early 20th century as urbanization covered the stream.
