NEW JACK CITY: ON TRACK FOR SUCCESS


The Portal Bridge is a key rail link between Newark, New Jersey, and New York City. The current bridge is centuries old and is a notorious bottleneck that has long caused delays for Amtrak and


New Jersey Transit trains due to its outdated swing mechanism and frequent malfunctions. The Portal North Bridge project is


an infrastructure development designed


to replace it with a new three-section bridge. The new bridge, a fixed-span structure, will eliminate several mass transit problems, improving reliability and efficiency along one of the busiest rail corridors in the country. It will be 15 metres (~50 ft.) above the water, allowing both land and water traffic to traverse the area simultaneously.


A significant milestone on the project


was reached when Mammoet successfully executed the transport of all three bridge sections for clients Skanska-Traylor JV and Carver Marine. They were moved from the assembly


site at Port of Coeymans to the roll-on location, where they were then loaded onto a barge for further transit down the Hudson River.


The sections each measure over 120


metres. Each was carefully transloaded onto a temporary mid-river staging called the transfer bent, before loading onto another barge prepared with Mammoet’s
