Interstate 384 is suburban freeway branching east from I-84 at the East Hartford/Manchester city line. Bypassing the Manchester city center to the south, I-384 extends into rural areas of Bolton, where it connects with U.S. 6 and U.S. 44 ahead of their separation to Willimantic and Putnam respectively.
Interstate 384 expands to eight overall lanes west from the parclo interchange (Exit 3) with Route 83 in Manchester to I-84 in East Hartford. 05/31/22
Interstate 384 was approved by the American Association of State Highway and Transportation Officials (AASHTO) on May 23, 1984 as a redesignation for I-84 between I-86 in East Hartford and U.S. 6/44 in Bolton Notch. I-86 was previously established in 1971 along what is now I-84 from East Hartford to Sturbridge, Massachusetts. I-84 was relocated then onto both the freeway taking U.S. 6 around Manchester and U.S. 6 along the Willimantic bypass further east. These two disconnected highways were part of the Interstate 84 proposal to join Hartford with Providence.1
Environmental concerns with constructing a freeway over Scituate Reservoir in Rhode Island resulted in the cancellation of I-84 in 1982. Connecticut subsequently dropped I-84 from plans by 1984.2
With the exception of the link between Silver Lane and I-84, the Manchester bypass was completed in 1971. The interchange with I-84 and adjacent Interstate 291 was built during a reconstruction project. The initial ramp opened with Interstate 384 in October 1986.1
