The highway was firstly designated as Interstate 82 (I-82) but was changed shortly after to its well-known designation, Interstate 84 (I-84). In 1970 through 1973, the first segments of the highway started construction, the segment now designated as I-384, and the Willimantic Bypass. When these isolated segments were completed, they were designated for the future Interstate, starkly different from today's signs. The signs remained on the Willimantic Bypass up to a decade after the cancellation of the project. The planned I-84 was going to also incorporate a cloverleaf intersection with I-295 in

, the main drinking supply for Providence. After conducting multiple other studies, including briefly considering an alternate southern alignment that would bypass the Scituate Reservoir to the south and connected I-84 to the Route 37 Expressway, Rhode Island ended up canceling their segment of the highway in 1982, which ended up causing Connecticut to cut the segment to I-395 in Plainfield. Without Rhode Island, the highway was fully canceled in 1983, and the mileage was returned for other projects. After the highway was canceled, the only inland route to Providence from Hartford was either US 44 or US 6. Many projects have since happened to improve the roads, mainly in Connecticut. One major one was improving the "Suicide 6" area of US 6 between

. Exits were renumbered to correspond with the rest of I-84 in Connecticut when the road was redesignated in 1984. The present I-384 as well as the present US 6 bypass near Willimantic, both of which were a part of what was then I-84's planned easterly continuation, were also numbered I-84 prior to 1984 even though they lacked any direct connection to the rest of I-84 at that time. (One had to use Silver Lane in East Hartford to travel between the two stretches of the highway.) These two sections were renumbered. The western segment became I-384, and the eastern one became part of US 6 when what was then I-86 was renumbered I-84.


Upgrades

Sections of I-84 in Connecticut were reconstructed and widened from the mid 1970s into the mid 1980s. Another section through Danbury was widened from four lanes to six lanes in 1985 and 1986. Widening of the highway through Danbury was funded by

, including a elevated section known as the Aetna Viaduct. Since it became apparent in the 1980s that this section of I-84 in Hartford was deteriorating, CTDOT has considered how best to repair or reconstruct the corridor. Since that time, many inspections have been carried out and frequent repairs made to keep the highway safe and functioning. In 2010, the Capitol Region Council of Governments (CRCOG), the City of Hartford, and CTDOT collaborated on a study of the corridor to begin the process of exploring reconstruction options. That study looked at several concepts, including the rebuilding of the viaduct "in-kind", as well as several reconstruction alternatives that would alter the configuration of the highway. The alternatives developed for that study were conceptual in nature—they did not look in depth at traffic, engineering feasibility, or environmental impact. However, the strong stakeholder input as part of that effort was helpful in leading to CTDOT's decision to initiate the I-84 Hartford Project, to build on the good work of that earlier study. The I-84 Hartford Project will be a full and comprehensive evaluation leading to a workable solution. The I-84 Hartford Project will examine the feasibility and assess the impact of a range of concepts. Following full examination of the impacts and benefits of feasible alternatives, and, in collaboration with stakeholders and the public, CTDOT will make a final decision on how to reconstruct this section of the I-84 corridor.
