The Bayonne Bridge is currently the fourth longest steel arch bridge in the world.
The Port Authority has released a report conducted by the U.S. Army Corps of Engineers, which points out that the Bayonne Bridge will begin to impose more and more restrictions on commercial shipping. Designed by master bridge designer Othmar Ammann and architect Cass Gilbert and completed in 1931, the span was at the time the longest steel arch bridge in the world, supporting a road bed of more than 8,000 feet, 1,675 feet of which hang from the arch with no intermediary support. However, its 165-foot height will no longer cut the mustard with todays larger ships, more and more of which are expected to pass through the region with the completion of upgrades at the Panama Canal to be completed in 2015. The Corps determined that the roadway could either be jacked up to 215 feet high, or, alternately, that the bridge could be knocked down and replaced with a tunnel. The Port Authority has devoted $10 million to figure out which is the best solution.
