The New Jersey Turnpike Authority (Authority) is planning to replace the existing Newark Bay Bridge (Vincent R. Casciano Memorial Bridge) with twin cable-stayed bridges as part of the Newark Bay-Hudson County Extension Improvements Program. The first (Westbound) bridge will be built online on the north side of the existing bridge and has a forecast construction duration of 2027 through 2031. To facilitate construction of this first bridge, a pair of inwater construction trestles (extending from each side of Newark Bay) are proposed to be built in two separate construction contracts. The first contract, Contract No. T835.770.204 (Newark trestle), will be built on the west side of the existing United States Army Corps of Engineers (USACE) maintained channel and the second, Contract No. T835.770.205 (Bayonne Trestle), will be built on the east side of the channel. The trestles will consist of a steel superstructure supported on steel pipe piles with a timber deck. Each will include a 45-foot-wide main spine, along with multiple 32-foot-wide trestle “fingers” that branch o, the main spine to facilitate bridge pier and superstructure construction.
