High Quality Content by WIKIPEDIA articles! The Portal Bridge is a rail bridge over the Hackensack River just west of Secaucus Junction in northeastern New Jersey, USA. The two-track, moveable swing-span between the towns of Kearny and Secaucus is owned and operated by Amtrak. It originally was built by the Pennsylvania Railroad and opened in 1910 in conjunction with service to the newly constructed Pennsylvania Station in New York City. The 100-year-old bridge is obsolete, limiting train speeds, and is so low that it often has to be opened to allow commercial boats to pass underneath, causing more delays. Work to replace the bridge is underway.
