Interstate 384 Connecticut

Interstate 384 Connecticut


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.

I-384 at Route 83 - Manchester, CT

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
