The Port Authority of New York and New Jersey has authorized a program to continue a multimillion-dollar upgrade of the road network at the agency’s New Jersey marine terminals.

The action will greatly improve efficiency and continue to make the port facilities more environmentally friendly by reducing truck congestion on the port’s aging roads, according to the authority.

The $105 million program includes the design, construction and realignment of portions of five major access roads to port terminals: Port, Corbin, Marlin and Kellogg streets and Doremus Ave. It includes the demolition and replacement of the Corbin Street Ramp, which has been the scene of accidents in the past three years.

The work will complement previous projects to widen McLester St. in the Elizabeth-Port Authority Marine Terminal, and widen and realign parts of Port St. and Brewster Rd. According to the port authority, the road improvement project will result in less truck congestion on port property and a corresponding reduction in harmful emissions produced by truck idling

The road improvement project will include new pavement for all of the roads, new center barriers, drainage, traffic signals, signs and curbing. When the projects are complete, the improvements will provide truckers and other port users with approximately $63 million in time-savings and reduced operating costs, and $1.2 million in safety benefits, over a 30-year period, says the authority.
