The Holland Tunnel was jointly commissioned by New York and New Jersey in 1906. However, the Hudson River crossings were originally conceptualized as a bridge. ASCE Metropolitan reports, “a bridge was not economically feasible due to the long span that would be required to cross the Hudson River, the deep foundations that would be needed to reach bedrock, and the lengthy approaches would necessitate the purchase of large amounts of real estate.”
