This project included the supply and erection of the main cables, suspender ropes, and suspended structure and decks on anchorages for a 2,910' (887m) suspension bridge with a 1,800' (549m) mainspan. The two main cables are 22 7/8" (581mm) in diameter. They were airspun in 37 strands of 296 wires each. The stiffening trusses are 17'9" (5.18m) deep, with a center to center width of 92'8" (28.2m). There are double suspender connections at every other panel point, 39'6" (12m) apart. The roadway is supported by 16 lines of 18" (457mm) stringers. The roadway is a 5" (127mm) filled steel grid. Throgs Neck is one of twelve major roadway bridges constructed by American Bridge in the New York City area. |
