Nova Scotia • Canada

The Nova Scotia Department of Public Works manages approximately 26,000 kilometers of provincial roads, including the Trans-Canada Highway through Cape Breton and the province's main arterial highways. Nova Scotia is the Atlantic gateway for Canadian freight, with the Port of Halifax — one of the deepest natural harbors in the world — handling significant container and vehicle traffic. Key freight corridors include Highway 104, Highway 102, and Highway 101. The department administers commercial vehicle permits, enforces axle weight regulations critical for protecting roads damaged by freeze-thaw cycles, and provides 511 Nova Scotia for road conditions. The province's ferry connections to Prince Edward Island and New Brunswick are also integral to regional freight flows.

Seasonal Restrictions Apr, May

Notable Rules

Nova Scotia's maximum height of 4.15 m is lower than the 4.30 m standard in western provinces, reflecting older bridge infrastructure. The Cobequid Pass (Hwy 104) is the primary commercial corridor from New Brunswick. Trucks must comply with restrictions at the Canso Causeway (Cape Breton access). Halifax is the primary Atlantic Canada freight terminal and container port.
