Windsor Locks is a town in Hartford County, Connecticut, United States. As of the 2010 census, its population was 12,498. It is the site of Bradley International Airport, which serves the Greater Hartford-Springfield region and occupies approximately 1/3 of the town. Windsor Locks is also the site of the New England Air Museum.
Located beside the Connecticut River and equidistant from the densely populated cities of Springfield, Massachusetts and Hartford, Connecticut, Windsor Locks is named for a set of canal locks that opened in 1829. Windsor Locks is situated just south of the first large falls in the Connecticut River, the Enfield Falls, which is the northernmost point that seagoing vessels can reach on the Connecticut River before transferring to smaller ships. The Enfield Falls Canal circumvents the Enfield Falls and its nearby shallows.
Originally part of Windsor, Windsor Locks broke off into its own settlement in 1854 after the thriving Enfield Locks going around Enfield Falls which opened in 1829. The Bradley International Airport opened as a military base in 1940, and opened to civilian use in 1947. In 1967 the town boundary was somewhat altered due to the opening of the Bradley Connector. The town boundary between Windsor Locks and Windsor changed several times and was altered with Windsor Locks being on the westbound side and the Windsor side on the eastbound side with the border on the median.
