The Cross-Harbor Rail Tunnel is a proposed freight rail tunnel under New York Harbor that would connect Jersey City, New Jersey, with Bay Ridge in Brooklyn, New York. The goal is to move cargo between New Jersey and Long Island more directly by rail, helping to reduce truck traffic through the city. The tunnel would be about 5.7 miles (roughly 9.2 kilometers) long and would use standard rail gauges to carry double-stacked container trains.

History and aim
Starting in the 1990s and earlier, planners explored ways to link rail freight across the harbor. In 2014, the Port Authority studied many options and narrowed the field to two main ideas: an enhanced railcar float operation and a basic rail tunnel. A phased plan suggested starting with the float operation and later building a full tunnel if warranted. A long process followed, with a Tier II environmental study launched in 2018, paused during the COVID-19 pandemic, and restarted in 2022.

Why it’s considered
Today, freight bound for New York City and Long Island must travel long detours across the harbor, and the region moves a relatively small share of freight by rail. The project would connect Long Island’s rail network more directly to New Jersey and the mainland, potentially cutting truck traffic and improving logistics for the region’s businesses.

Alternative options and costs
Two main options remain under study: an enhanced railcar float (a system of moving railcars by water) and a full rail tunnel. The water-based float option would cost far less (on the order of a few hundred million dollars) but would carry less freight. A full tunnel would cost several billion dollars. The studies call for a cautious, phased approach—start with the float system to build capacity and intermodal facilities, then plan and fund a possible tunnel if demand justifies it.

Current status and challenges
The plan has faced questions about price, demand, and who would manage land use around a potential terminal. Local communities have raised concerns about noise, vibration, and traffic, and some oppose locating a large transshipment area in their neighborhoods. The Port Authority has weighed the project against other major investments, like passenger rail projects, when deciding how to allocate funding. Critics worry that a very costly tunnel might not deliver enough benefit to justify the expense.

In summary, the Cross-Harbor Rail Tunnel is a long-running effort to create a direct freight link between New Jersey and Brooklyn to serve Long Island, with a phased path that could begin with water-based railcar movements before committing to a full tunnel if justified by future freight demand.
