Bordering States

New York

To the west, Connecticut shares a border with New York, stretching over 90 miles from the Long Island Sound in the south to the northern limits near the Housatonic River. This border is integral to Connecticut’s economy and transportation network, as its proximity to New York City places southwestern Connecticut, particularly Fairfield County, within the greater metropolitan area. Cities like Stamford, Greenwich, and Norwalk function as affluent suburbs of New York City, and the region is home to numerous commuters who work in Manhattan. The close relationship between Connecticut and New York fosters significant cultural and economic exchange, particularly in finance, education, and entertainment industries.

The natural border formed by Long Island Sound also provides Connecticut access to coastal resources and maritime activities that complement New York’s maritime industries. Both states benefit from the shared use of waterways and regional infrastructure, such as rail systems and highways that connect Connecticut residents with New York City. The counties near this border are among the wealthiest in the United States, largely driven by the financial industries centered in Manhattan.
