John A. Harris

Remember 6sqft's post about a madcap engineer who wanted to pave over the East River in 1911 in order to create a "Mega-Manhattan?" Well, 13 years later, John A. Harris, deputy police commissioner in charge of traffic, came up with his own proposal for incorporating the river into the streetscape of the city: draining it entirely.

It would have transformed the waterway into "a five-mile system of automobile and motor-truck highways, subway lines, parking spaces, and city centers." Two concrete dams were to be erected, one near the Williamsburg Bridge and one near Hell Gate, and the riverbed would be "bridged with levels supported by steel uprights," thereby connecting the four boroughs.
