From Hamden, prospective route(s) and time(s) vary based on potential starting point. To drive to Waterbury, traveling via New Haven is an unusual option (e.g., never from northern Hamden where back roads to Rt 8 or travel via Cheshire to I-84 may be alternatives; Centerville or Spring Glen neighborhoods via Rt 15 to Woodbridge to Seymour via Rt 8 to Waterbury; maybe only travel via New Haven if near Hamden/New Haven border).
