Interstate 691 began as a freeway for U.S. 6A between Exits 8 and 13 in 1965. By 1969, the designation shifted from U.S. 6A to Connecticut Route 66, with construction extending the road west to Exit 4 by 1970. Interstate 691 was established by the American Association of State Highway and Transportation Officials ( AASHTO) along with I-284 in Hartford on July 13, 1976. I-691 however was not signed until 1987, one year prior to the completion of its connection to Interstate 84.1
