Abstract:

Aerial tramways are not normally considered for a cross-town mass transit system. They are no longer limited to the ski resorts since construction of the link between Manhattan Island (New York City's business hub) and a large new residential development on Roosevelt Island in the middle of the East River. The 3,100 ft (945 m) trip station to station will have a travel time of 3.5 minutes. The cable car capacity is 125 passengers, the largest in the world. Space limitations are severe in a city center, so the three towers of space truss construction required special design consideration.
