Interstate 395 (abbreviated I-395) is a 67-mile-long north–south Interstate Highway that begins at Interstate 95 in East Lyme, Connecticut running northwards through Connecticut's Quiet Corner, and ends at Interstate 90 in Auburn, Massachusetts, where I-395 becomes Interstate 290. The original designation for the portion of Connecticut's I-395 that was part of the Connecticut Turnpike was Route 52. Route 52 was slated to become a southward extension of Interstate 290 before it received the I-395 designation in 1983.
