Manitoba • Canada
Manitoba Transportation and Infrastructure manages over 19,000 kilometers of provincial highways in a province that serves as Canada's central hub for north-south freight movement on the CANAMEX Corridor. Key freight routes include Highway 1 (Trans-Canada), Highway 75 (connecting to the US border at Emerson), and the Perimeter Highway around Winnipeg. Manitoba's strategic position between Ontario, Saskatchewan, and the US Midwest makes it a critical transit province for grain, potash, and manufactured goods. The department administers commercial vehicle permits, provides Manitoba511.ca for road conditions, and manages seasonal weight restrictions critical during spring thaw on rural roads.

Special Exemptions
Notable Rules
Manitoba permits B-train combinations up to 27.5 m on designated highways. Grain transport is economically vital — agricultural exemptions are broadly applied. The Trans-Canada Highway (Hwy 1) and PTH 75 (Pembina Highway to the US border at Emerson/Pembina) are primary commercial corridors. Weight restrictions on secondary (PTH/PR) roads are more restrictive than main highway limits.
