History

1941

Route 3 was established in 1941. It originally ran from West Street/Berlin Road inCromwell,which was part ofRoute 72at the time (nowRoute 372), to theSilas DeaneHighway (Route 99) inWethersfield.

1958-1973 (I-491)

In late 1958, as part of the plannedInterstate 491(a southeastern bypass ofHartford), a freeway from I-91 to Main Street in Glastonbury, crossing theConnecticut Riveron thePutnam 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. In the late 1980s, the freeway was extended so that it terminated at Route 2, rather than at Main Street.

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 atRoute 66) was reassigned to Route 3.

Major intersections

As part of an upcoming sign replacement project on Route 3 between I-91 and Route 2, new mile-based exit numbers will be added along that stretch of expressway.
