Interstate 384 (I-384) is an auxiliary Interstate Highway located entirely within the state of Connecticut. It runs east to west, going from I-84 and I-291 in East Hartford to US Route 6 (US 6) and US 44 in Bolton. Route description I-384 officially begins at I-84 eastbound exit 59 at the East Hartford–Manchester town line, as the right two lanes of traffic split from the I-84 mainline. The highway can also be accessed from the I-84 eastbound high-occupancy vehicle lane (HOV lane), and westbound I-384 traffic can also access the HOV lane on westbound I-84. Westbound I-84 access to I-384 is provided through a complex interchange that also provides access from Pleasant Valley Road near The Shoppes at Buckland Hills and from I-291. I-384's first exit is for Spencer Street. The eastbound ramp is on the I-384 mainline, while the westbound ramp comes from a split in the I-84 interchange ramp. Just east of the Spencer Street overpass, the ramp from westbound I-84 joins the I-384 mainline and the HOV lane becomes a conventional lane. I-384 continues along the southern part of Manchester. It has one interchange before it intersects Route 83, which provides access to Manchester Center. After one more interchange in Manchester, it crosses into Bolton, where it has a partial interchange with Route 85. Shortly after the interchange, I-384 ends as it meets the US 6/US 44 concurrency just west of its eastern split at Bolton Notch. The highway is eight lanes wide west of Route 83, six lanes wide to Route 85, and four lanes wide for the rest of the highway's duration. Special designations Since May 31, 1996, the segment of I-384 "running from the junction of Interstate Route 84 in Manchester in a general easterly direction to Route 6 in Bolton" has been officially known as the State Trooper Russell A. Bagshaw Highway, in memory of a Connecticut State Police trooper who was killed in the line of duty in 1991. History Prior to 1984, I-384 was designated I-84. During that time, current I-84 east of the East Hartford junction was I-86. Originally, the freeway was supposed to end in Johnston, Rhode Island, at the I-95/I-195 connector (now the Route 6-10 Connector). The freeway was built to Bolton where it abruptly ends at the intersection with US 6 and US 44. A segment from Columbia to Windham was also built, forming the present-day US
