This project was for construction services for structural improvements for the Robert F. Kennedy Suspension Bridge (formerly the Triborough Bridge) over the East River in New York City. The suspension bridge is 2,723’ (830m) long with eight lanes. The work on the bridge included the fabrication and installation of structural protections for hanger ropes and main cables, and structural steel tower reinforcements and protections. The materials utilized for the cable protection were special, for the purpose of resisting force. All work was undertaken during full operation of the bridge. American Bridge was responsible for all maintenance and protection of traffic. All AB personnel were subject to background checks and daily security clearances. The saddles, main cable, and suspender cables for this bridge were originally constructed by American Bridge in 1936 under AB order no. G-5504-10. The suspender ropes and the deck of both the suspension bridge and the Queens Viaduct approach were replaced by American Bridge in 2004 under AB order number 610110.
