CTDOT
Connecticut • United States of America
The Connecticut Department of Transportation (CTDOT) manages approximately 4,200 miles of state highways within one of the most densely trafficked and economically concentrated regions of the United States. Key corridors for freight include I-95, I-84, I-91, and the Merritt Parkway — though the latter has height restrictions making it impassable for most commercial trucks. CTDOT coordinates with neighboring states to facilitate seamless freight movement across the Northeast. The department administers commercial vehicle weight and permit regulations, and its CTroads.org system provides real-time traffic information essential for trucking operations through the congested New England corridor.

Notable Rules
Connecticut allows higher axle weights on paved state roads (22,400 lbs single, 36,000 lbs tandem). The I-95 corridor through the state is one of the most congested freight routes in the northeast. I-84 connects Hartford to New York and New England. Many local roads and older bridges have strict weight restrictions.
