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 Hartford, 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. Exit list Exits are currently sequential but are planned to be converted to mileage-based exit numbering in 2025.
