3. Queensboro Bridge Trolley Kiosks
A trolley used to run between Queens and Manhattan over the Queensboro Bridge, with a mid-span stop which would take riders to Roosevelt Island via elevator or stairs. Though the system was phased out in the 1950s, a trolley terminal remained on the Manhattan side of the Queensborough Bridge approach ramp. Cars kept crashing into the deteriorating structure so it was moved to become the entrance of the Brooklyn Children’s Museum in 1970. The 2004 museum renovation didn’t include plans for the renovation so the structure was moved to Roosevelt Island to become the visitors center for the Roosevelt Island Historical Society.
