The Long Island Sound link is a proposed bridge or tunnel that would connect Long Island, New York, to Westchester County or Connecticut, across Long Island Sound. The project, intended to improve access to Long Island and relieve traffic congestion in New York City, has been studied and debated since the mid-20th century. Proposals have varied in location and form, ranging from a western crossing between Oyster Bay and Rye, to more easterly routes linking Suffolk County with Connecticut.
