// Strategic Significance
The Mario Cuomo Bridge formerly Tappan Zee Bridge is the widest bridge in the world crossing the Hudson River carrying I-87 and I-287 between Rockland and Westchester Counties north of New York City. The new bridge replaced the original 1955 span that had exceeded its design life. The bridge is critical to suburban New York City commuter and freight movement.
// Civilian Impact Assessment
Hudson Valley with 2 million residents north of NYC. The bridge is the primary Hudson River crossing for the I-87 and I-287 corridors. Closure would force major detours affecting millions of commuters and freight carriers.
