The New Jersey and Staten Island approach viaducts are supported by several dozen concrete arches and measure 3,010 and 2,010 feet respectively. The profile of the arch increases in depth from crown to abutment, with 37-and-a-half-foot-deep trussed ribs at the top and 67-and-a-half-foot ribs at the ends. Until the ongoing reconstruction, the deck it supported was close to 50 feet in width. The hyperbolic curve of the 325-foot-tall, 85-foot-wide steel arch runs 1,675 feet from shore to shore. An estimated 12 percent of all international containers entering the United States pass under the bridge. Combined, the ports produce close to 270,000 direct and indirect jobs and nearly $11 billion in annual wages. The Kill Van Kull is among the key shipping channels in the third-busiest port on the East Coast, providing access for oceangoing container vessels to New Jersey’s Port Newark-Elizabeth and Staten Island’s Howland Hook marine terminals.
Looking north from Staten Island towards Bayonne, NJ The Port Authority expects the Bayonne project to generate around 2,800 construction industry jobs with between $240 and $380 million in wages. and Kiewit Infrastructure Co., which are also collaborating on the Kosciuszko Bridge replacement span over the Newtown Creek between Brooklyn and Queens.
The principal contractors are Skanska Koch, Inc. The Navigational Clearance Project is expected to cost $1.3 billion. To keep up with the canal’s expansion, slated to open later this year, the Port Authority is raising the bridge roadbed from 151 to 215 feet above the mean water level. If the Port of New York and New Jersey fails to accommodate such vessels, the nation’s largest metro area would suffer considerable economic damage.
The suspended roadbed of the 84-year-old Bayonne Bridge, which spans the Kill Van Kull strait between Staten Island and Bayonne, N.J., is too low for passage of the latest, giant container ships built to traverse the expanded Panama Canal locks. But given New York’s position as a global economic hub, it is not surprising that one of the city’s largest engineering efforts is a direct response to a megaproject 2,200 miles away. In general, new construction reflects local real estate demand and community needs.
