The New NY (Tappan Zee) Bridge is being designed to replace the old bridge that is deteriorating and unable to handle the current traffic demands. The new bridge will have separate east and west bound structures with a 100-year service life. It will feature cable-stayed bridges with composite decks, stay cables, V-shaped towers, and reinforced foundations. The design includes redundancy to ensure operational and structural safety, allowing for traffic adjustments and localized damage without collapse.
