Delaware • United States of America
The Delaware Department of Transportation (DelDOT) manages over 13,000 lane miles of roads in the nation's second smallest state, yet one of its busiest freight corridors. Delaware sits on the I-95 corridor linking the mid-Atlantic to New England, making it a critical transit zone for trucking operations. DelDOT maintains the interchange systems connecting I-95, I-295, US-13, and the Delaware Memorial Bridge. The department oversees commercial vehicle weight limits, oversize permits, and operates a weigh station network. Its 511 system provides real-time traffic data to freight operators navigating the region.
