Connecticut

There is some unused pavement to the east of a
Route 7 before the road was extended to exits 11 and 12 in Brookfield
in the 1970s.

I-91 was widened^[1] from 3 to 4 lanes, leaving two strips of unused pavement. [1]

Related to the Rocky Hill entry, the junction of Interstate 84 and Route 9 is a four-level stack interchange, only half of which is used. The interchange was originally built for Interstate 291. The northern half was cancelled in the early 1970s due to opposition regarding drinking water reservoirs near the proposed path.^[1] The interchange stood wholly unused for over 20 years, until Route 9 was extended in 1992 to use the south-facing part of the interchange. Route 9 ends at I-84, so the north-facing and through ramps remain unused.^[2] Viewable at [2].

Exit 45 for
Route 504 on Interstate 84 is incomplete, lacking a ramp for each direction on I-84. The interchange was planned to be a short freeway, named the Cedar Ridge Connector, to the Berlin Turnpike.^[3] It has a stub exit [3], wide shoulders [4], and a large median [5]
.

Exit 43 for Route 501 on Interstate 84 has a stub and a wide median near the intersection of Park Road, as it was originally planned to head farther north as the Trout Brook Connector.^[5] [7]

Route 11 has a stub continuation at its southern end for a once-proposed continuation southward to Interstate 95 at Interstate 395.^[6] [8]

Interstate 91 and Interstate 95. The highway ends abruptly, after only 3 exits, becoming North Frontage Road. The rest of Route 34 continues along surface streets through the city. Opened in May 1960,^[8] the plan was to have Route 34 continue as an expressway under the Air Rights Garage (which was specifically built to accommodate the highway)^[7] and along the right of way (created by relocating homes and businesses in the area when the highway was in construction from 1955 to 1960^[8]), complete with frontage roads, to Derby.^[7] Plans also existed to extend the highway to New York state^[7]^[8] or a shorter route to Route 15/Merritt Parkway^[8] existed even through the 1990s, but the project was shelved completely when the Pfizer building was built on the right of way directly past the Garage.^[9] [9] The original plan of Route 34 will never go through, but the city still desires a similar connection. The city is now in the process of demolishing the existing Route 34 Connector west of its bridge over the New Haven Railyard and replacing it with a landscaped boulevard with at-grade intersections.[10]
Further west in Orange, a short section of the proposed Route 34 freeway extension was built in the late 1980s, which now serves as a commuter parking lot after freeway plans were cancelled.

There is grading on the Willimantic Bypass just east of its western terminus for where the proposed Interstate 84 was to join the Bypass. A loop ramp to I-84 westbound has clearing and a dirt path for where it was to run. The I-84 mainline also has grading on eastbound US 6.
At the east end of the Bypass, there is also grading for I-84's continuation to the east towards Providence, Rhode Island.
