Interstate 691 Connecticut


Interstate 691 is a relatively short freeway that connects Interstate 84 in Southington with Interstate 91 in Meriden. The freeway provides a halfway boundary between greater Hartford and greater New Haven; it was completed by the late 1980s, although some sections were open in the 1960s.

Connecticut 66

Interstate 691 extends east of Interstate 91 as Connecticut 66 in Meriden. According to Kurumi's Connecticut Interstate 691 page, the freeway was planned for further extension east via Connecticut 66, but that plan has not been considered for some time.


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 66, with construction extending the road west to Exit 4 by 1970. Interstate 691 was established by AASHTO along with Interstate 284 in Hartford on July 13, 1976. Interstate 691 however was not signed until 1987, one year prior to the completion of its connection to Interstate 84.1
