The new Third Avenue Bridge, fabricated in Alabama, was floated to the Bronx in July (ENR 7/19 p. 14). It was tethered to temporary posts about 200 ft south of its permanent home while crews with the local office of Kiska Construction Corp. rebuilt three Harlem River piers in an $118-million contract.
The new center pier is about 100 ft x 60 ft with a reinforced concrete cap and is supported by six 10-ft-dia drilled shafts, says Paul Connolly, project manager for Hardesty & Hanover, New York City. The firm provided design and construction support services.
