After years of planning, engineering is underway for a 4.5-mile-long Hudson Tunnel Project between New York and New Jersey, following a grant from the Federal Transit Administration that could eventually reach $6.88 billion.
The Gateway Development Commission and the U.S. Dept. of Transportation announced the start of the tunnel's engineering phase on July 6. The commission estimates the total cost of the tunnel at $16.1 billion, while the Federal Transit Administration sets the figure closer to $17.2 billion.
