Department of Transportation and Infrastructure
DTI
New Brunswick • Canada
The New Brunswick Department of Transportation and Infrastructure (DTI) manages approximately 18,200 kilometers of provincial roads, serving a province that is a critical transportation gateway between Quebec, Nova Scotia, and the northeastern US. Key freight corridors include Highway 1 (Trans-Canada), Highway 2, and Highway 11. New Brunswick's Port of Saint John is a major deep-water port for bulk commodities and an important transit point for US-bound Canadian goods. DTI administers commercial vehicle permits, provides the 511NB road conditions system, and manages critical ferry connections. The department plays a key role in facilitating cross-border truck traffic at the Woodstock, St. Stephen, and Edmundston border crossings.
