Connecticut Route 10 is a state highway that runs between New Haven and the state line near Granby.

Route description

Route 10 begins at Interstate 95 (I-95) as Ella T. Grasso Boulevard in the city of New Haven. It then passes by Southern Connecticut State University before entering the town of Hamden along Dixwell Avenue. Route 10 continues north through the towns of Cheshire, Southington, Plainville, Farmington, Avon (where a lengthy concurrency with US 202 begins), and Simsbury. The Southington section of Route 10 was dedicated on Aug. 6, 1960 (and rededicated on Oct. 6, 2007) as the Louis G. Tolles Memorial Highway in honor of the late Southington native and leader of the Connecticut State Grange (1885–1956).

History

Route 10 originally followed a different route south of Granby, Connecticut, starting in the town of Old Saybrook^[2] instead of at its current New Haven terminus. It moved to its current alignment along the Connecticut section of the College Highway in 1932, with the former alignment becoming the original Route 9. The original routing is now Routes 154, 99, and 189. During the 1960s Connecticut planned on building an expressway along the Route 10 corridor, but the only part of this plan actually constructed was Route 40 in the Mount Carmel area of Hamden, as well as several exit ramps connecting Route 10 to I-84 southwest of Hartford.
