Interstate 384 follows a seven mile freeway spur east from I-84 & U.S. 6 at East Hartford to U.S. 6 and 44 at Bolton. The freeway was planned in the 1960s as part of U.S. 6 expressway crossing the state east to Providence, Rhode Island. An addition of 1,500 miles to the Interstate system in October 1968 included an allocation for an Interstate between I-84 in East Hartford and Providence at I-95. The route would supplant U.S. 6 along this corridor and was designated as a relocation of Interstate 84, with existing I-84 northeast to Sturbridge, Massaschusetts reassigned as Interstate 86.1
Construction of the new Interstate 84 alignment commenced in 1968 on the two portions that exist today. The Manchester bypass (what is now I-384) was completed in 1971 and the 5.8-mile long Willimantic bypass (the eventual mainline of U.S. 6) opened in 1973. Subsequent sections of I-84 freeway remained in the planned stages, with resistance mounting due to concerns about impacts to both Nathan Hale State Forest in Connecticut and Scituate Reservoir in Rhode Island. This led to the cancellation of I-84 in Rhode Island and a September 1983 exchange of Interstate mileage by ConnDOT for the Connecticut 52 freeway, which became a part of Interstate 395.1
As approved by AASHTO on May 23, 1984, Interstate 84 shifted officially back onto its prior alignment northeast from East Hartford to Massachusetts. The Manchester bypass portion of freeway was designated as Interstate 384 and the Willimantic bypass was downgraded from I-84 to a realignment of U.S. 6. The westernmost portion of I-384 was not directly connected to I-84 until 1986.1
