Recognized by AISC as the most beautiful steel bridge in its class in 1931, the Bayonne Bridge connecting Staten Island, N.Y., with Bayonne, N.J., is poised for a serious makeover.
Officials have released additional information about the proposed $1 billion Bayonne Bridge project which will replace the existing roadway with a new deck about 60 feet higher up the arches to allow taller ships to pass.
The New Jersey On-line website www.nj.com reports the project is envisioned as “a widening of the four traffic lanes from 10 to 12 feet each, along with the addition of shoulders, and a center divider that will replace what is now just a double-yellow line.”
The report also shares comments from Peter Zipf, chief engineer for the Port Authority of New York and New Jersey, describing one possible approach to the challenging construction. “The two inner lanes will be closed to traffic and used as a staging area where a crane will likely be used to hoist a series of 84-ft-wide girders into place, forming the steel structure underpinning the new roadway. Like the original, the new roadbed will be suspended by steel cables from the bridge’s original 79-year-old arch. The two existing outer lanes will remain open, shielded from the work overhead, providing one traffic lane in each direction. To rise to the level of the higher roadbed, the bridge approaches will be made slightly steeper and longer, constructed in a similar method from staging areas on the original approaches.” To read more, click here.
