Route 3 is a 14.48-mile-long (23.30 km) route connecting Middletown to the Glastonbury-East Hartford town line. It passes through the towns of Cromwell, Rocky Hill, Wethersfield, and Glastonbury. The northernmost 3 miles (4.8 km) of Route 3 is an expressway that was originally intended for the cancelled Interstate 491.

Route description

Route 3 begins at Route 66 in Middletown. It is a secondary, minor arterial road from Middletown up to its interchange with Interstate 91 in Wethersfield. It crosses, but does not have a direct interchange with the Route 9 freeway in Cromwell (access is via Route 372) and with Interstate 91 in Rocky Hill. The last 3.5 miles (5.6 km) of Route 3 from the Interstate 91 interchange in Wethersfield to East Hartford is freeway. Then Route 3 freeway crosses the Connecticut River on the William H. Putnam Memorial Bridge from Wethersfield into Glastonbury. The freeway has one intermediate exit into Glastonbury. Route 3 ends at an interchange with the Route 2 freeway just after crossing into East Hartford. The last 0.75 miles (1.21 km) of Route 3 is the merging ramp from Route 3 northbound to Route 2 westbound.

History

1941

Route 3 was established in 1941. It originally ran from West Street/Berlin Road in Cromwell, which was part of Route 72 at the time (now Route 372), to the Silas Deane Highway (Route 99) in Wethersfield.

1958-1973 (I-491)

Interstate 491
Location:	Hartford, Connecticut
Existed:	1958–1973

In late 1958, as part of the planned Interstate 491 (a southeastern bypass of Hartford), a freeway from I-91 to Route 2, crossing the Connecticut River on the Putnam Memorial Bridge, was opened. The Route 3 designation was temporarily extended along this freeway pending completion of I-491. In 1973, I-491 was cancelled due to local opposition and the Route 3 designation along this freeway segment became permanent.

1991

In 1991, when the Route 9 freeway through Berlin and New Britain was completed, Route 72 was truncated to end at Route 9 in New Britain. The east–west portion of the old alignment of Route 72 was reassigned to an extended Route 372 (running along Berlin Road/West Street to end at Route 99 in Cromwell). The north–south portion of old Route 72 from Cromwell to Middletown (ending at Route 66) was reassigned to Route 3.
