If the future really is one full of self-driving cars, computer-directed trucks and sky-riding drones, doesn’t that mean there will be a lot less need for the city’s choked highways? The designers at Skidmore, Owings & Merrill are preparing for that future with a radical reimagining of one of Robert Moses’ least-loved legacies: the invariably jammed Brooklyn-Queens Expressway. Envisioning the world’s first “autonomous electric superhighway” that generates its own power to propel vehicles, the designers call for burying the portion of the roadway that slinks past Cobble Hill and covering it with new housing. The remaining elevated portion would be shrunk to three lanes—half its current width—and replaced with at-grade boulevards, parks and commercial and residential development.
