Construction Underway on $1B Portal Bridge in NJ
Abstract
The Portal North Bridge Project will replace the existing elevated bridge with a two-track, high-level, fixed-span bridge. The project spans 2.44 miles of the Northeast Corridor rail line. The main span will be 1,200 ft long and consist of three tied arches, each 400 ft long x 57 ft wide x 86 ft high. The existing bridge's lowest beams are 23 ft above the Hackensack River. The new bridge’s 50-ft clearance will allow marine traffic. The horizontal clearance will improve from 90 ft to 270 ft. The 50-foot clearance will also allow marine Traffic to pass underneath without delays. Completion is expected in about 5.5 years.
