Ministry of Transportation
MoTT
British Columbia • Canada
British Columbia's Ministry of Transportation and Transit manages over 47,000 kilometers of provincial highways connecting Pacific ports to the Canadian interior and US border crossings. Key freight corridors include the Trans-Canada Highway (Highway 1), the Coquihalla Highway (Highway 5), Highway 97, and the Yellowhead Highway (Highway 16). The Ports of Vancouver and Prince Rupert — Canada's largest container gateways — depend on BC's highway network to move goods to the national rail network and distribution centers. The ministry administers commercial vehicle permits, manages the DriveBC.ca road condition system, and oversees critical mountain pass monitoring for freight carriers transiting the Coast and Rocky Mountains.
