The Governor Mario M. Cuomo Bridge was needed because the number of vehicles crossing the bridge every day far exceeded the number the previous bridge was designed to handle, traffic jams and delays were a regular occurrence, accident rates were high and maintenance costs on the old bridge were expected to be three to four billion dollars over the next 20 years. The bridge carried 140,000 vehicles daily. Approximately 50 million vehicles crossed the Tappan Zee Bridge in 2016.
The new bridge was designed and constructed to last 100 years without major structural maintenance. It is a visually striking, recognizable landmark and one of the widest cable-stayed structures of its kind in the world.
The Governor Mario M. Cuomo Bridge features eight general traffic lanes, four emergency shoulders, dedicated bus lanes, a shared bicycle/pedestrian path and a state-of-the-art traffic monitoring system. The new crossing also has the structural capacity to handle rail in the future.
