The 116-Year-Old Tunnel New York Can’t Afford to Lose

Nearly 200,000 passenger trips depend on two railway tubes beneath the Hudson River that opened in 1910. New York cannot properly rebuild them without first constructing an entirely new tunnel. The North River Tunnel remains safe for operation, but Superstorm Sandy flooded both tubes with millions of gallons of salt water in 2012. The contamination left behind continues to damage concrete, cables, track equipment and other essential systems. Closing just one existing tube for long-term repairs would force trains traveling in both directions to share the remaining track, severely reducing capacity between New Jersey and Manhattan. The roughly $16 billion Hudson Tunnel Project solves that problem by constructing two new single-track tubes first. Once trains move into the new tunnel, the original tubes can finally be rehabilitated one at a time. In this documentary, we explore: How engineers constructed the original tunnel beneath the Hudson Why Superstorm Sandy continues to affect it Why weekend maintenance cannot complete the necessary repairs How enormous tunnel-boring machines build new railway tubes Why engineers are stabilizing the Hudson River bed How ground freezing protects difficult Manhattan excavations How the tunnel connects beneath Hudson Yards Why railway redundancy matters to the entire Northeast Corridor The new tunnel is currently expected to open in 2035, followed by completion of the original tunnel’s rehabilitation in 2038.
