Portal Bridge

The Portal Bridge is a railroad bridge over the Hackensack River in northeastern New Jersey, United States, just west of Secaucus Junction. It is a two-track, moveable swing-span between the towns of Kearny and Secaucus owned and operated by Amtrak as part of the Northeast Corridor and also used by New Jersey Transit., it was considered the busiest train span in the Western Hemisphere, carrying between 150,000 and 200,000 passengers per day.Originally opened in 1910, the bridge was built by Pennsylvania Railroad in conjunction with service to the newly constructed Pennsylvania Station in New York City.The bridge is considered obsolete and under review for replacement. Currently, the bridge limits train speeds to 60 mph and is so low that it often has to be opened to allow commercial boats to pass underneath it causing more delays. For these reasons, it has been called the Achilles' heel of the Northeast Corridor. Existing design and engineering plans for the bridge's replacement call for two fixed bridges.Work on the replacement bridges has stalled due to lack of funding and as of 2014 funding for the $940 million to build it had not been identified.
