The sections - each measuring more than 120 metres in length - were moved from the Port of Coeymans assembly site to a roll-on location before being loaded onto barges for transport down the Hudson River. The company employed its Mega Jack system for the lifting operations, along with slide track systems for final positioning.

The new fixed span bridge will replace the existing 100 year old Portal Bridge between Newark, New Jersey, and New York City. When complete, it will sit 15 metres above the water, allowing simultaneous rail and water traffic movement.

Project manager Sidney King said: "Our team combined extensive experience and technical expertise to support this first major milestone for the Portal North Bridge project. The bridge section's relocation and successful loading onto the barge demanded careful planning and close coordination with Skanska and Carver, and we're proud to report a seamless operation."

The installation process involved loading each section onto a temporary mid-river staging area before transferring them to a barge equipped with the Mega Jack system. The sections were then jacked up between 14 and 16 cassettes high before being positioned using tugboats and winches. The East and West bridge sections required additional positioning using Mammoet's slide track systems.
