The Transformational Network is where we explore the major expansions — new trunk lines, cross-borough connections, and large-scale corridor upgrades that would radically change how New Yorkers move. These are the big-build projects that eliminate transit deserts, unlock entirely new travel patterns, and create true system resiliency through redundancy — ensuring the city can keep moving even when a major corridor or tunnel goes down. This is long-horizon infrastructure designed to reshape the subway map, expand access to opportunity, and future-proof New York’s transit network for the next century.
