History

The current I-291 is only the northeastern arc of what was originally planned as a three-quarter beltway around Hartford. From Windsor, I-291 would have continued to cross

again in Farmington, and end at

in Rocky Hill. While the remainder of I-291 was canceled amid environmental concerns, those two interchanges were built as part of I-84 and I-91 construction and stood unused for over 20 years as ramp stubs. Half of the stack interchange at I-84 was eventually placed in service when Route 9 was extended to run along a portion of the I-291 right of way south of I-84 in 1992. The I-91 ramp was demolished in 1999 during an expansion project. The northernmost of the Route 9 expressway follows the original path of the southwest segment of I-291 from I-84. Route 9 currently serves as the southwest quadrant around Hartford leaving only the northwest section of I-291 unbuilt. Route 218 is a four-lane divided arterial route serving what would have been the northwest quadrant of the I-291 beltway. When the interchange with I-91 was completed in the early 1990s, a pair of ramp stubs connecting I-291 to Route 218 were built to the west of I-91 in anticipation that the northwest leg of I-291 might eventually be built. Over the years, there have been discussions of constructing a multilane surface road from the I-84/Route 9 stack interchange to Route 218 to complete the northwest bypass of

, but funding and potential impacts to the reservoirs that supply Hartford with much of its drinking water have prevented anything from being built north of I-84. The CTDOT headquarters was built on land originally acquired for I-291 where it would have intersected US 5/ Route 15 in Newington. A small portion of what was to be the northwest leg of I-291 was built along Route 218 west of I-91, which is now used as a commuter parking lot.
