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

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 3 begins at Route 66 in Middletown, and is a secondary, minor arterial road for its first 11 miles (18 km) up to its interchange with Interstate 91 in Wethersfield. After crossing into Cromwell, it intersects Route 372, which offers access to Route 9 just east of the intersection. After overpassing Route 9, it continues north into Rocky Hill and overpasses Interstate 91 without an interchange (access is via West Street [SSR 411]). After a brief concurrency with Route 160, it crosses into Wethersfield, where it meets the eastern end of Route 287 and crosses over Route 99. After the Elm Street intersection, it becomes a freeway for the last 3.5 miles (5.6 km). After a partial interchange with Interstate 91 (no direct access to I-91 South from Route 3 North), it crosses the Connecticut River on the William H. Putnam Memorial Bridge into Glastonbury. The freeway has one exit for Main Street (via Glastonbury Boulevard northbound and Putnam Boulevard southbound) before ending at a trumpet interchange with the Route 2 freeway at the East Hartford town line. The last 0.75 miles (1.21 km) of Route 3 is the merging ramp from Route 3 northbound to Route 2 westbound.
