The Queensboro Bridge was made famous by the Simon & Garfunkel song "Feeling Groovy." The bridge has an aura of good feeling, with an elevated subway " originally an electrified trolley line and perimeter bicycle and walking paths. A cable car to the north allows for a low-flying bird's-eye view of its exposed steel and its structural expressiveness. Designed by engineer Gustav Lindenthal with help from architects Palmer and Hornbostel, the bridge opened to traffic in 1908, connecting Manhattan to the wilds and fields of Long Island City and the bucolic splendor of Queens, Nassau, and Suffolk counties beyond. There were no morning traffic jams at that time. Any number of films have featured the bridge as the favored entry point, by car, into Manhattan. Now congestion pricing tolls are under discussion for both this bridge and the three other free bridges that cross the East River.
