Gowanus Canal: Hamilton Avenue Bridge
This southernmost crossing of the canal is another two-for-one bridge, with the Gowanus Expressway on the upper viaduct and the Hamilton Avenue bascule drawbridge directly below it. The drawbridge contains two separate parallel spans (one for eastbound, one for westbound - NYC BIN #2240231/2). This has been a very popular crossing point since the canal was a creek and a number of different bridges have been built here since the mid 19th century, including bascule bridges in 1905 and 1942. It was renovated around 2005, although I'm not sure how much of the 1905/1942 bridge (if any) was incorporated into the renovation.
