Prince Edward Island • Canada
The Prince Edward Island Department of Transportation and Infrastructure manages approximately 3,700 kilometers of provincial roads across Canada's smallest province, connected to mainland New Brunswick by the Confederation Bridge — the longest bridge over ice-covered waters in the world. The Confederation Bridge (Highway 1) is the critical freight link for trucking on and off the island, as it replaced the ferry service for most commercial freight. PEI's agricultural economy (famous for potatoes and seafood) relies on efficient truck transport to mainland markets. The department administers commercial vehicle regulations, manages bridge weight limit compliance, and provides 511PEI road condition information for commercial operators.

Notable Rules
The Confederation Bridge (13 km, connecting PEI to NB) is the sole fixed link to the mainland. Vehicles exceeding 4.88 m height or specific overwidth dimensions require pilot cars and advance coordination with the Confederation Bridge Authority. Potato and agricultural transport are the dominant freight categories — PEI is Canada's leading potato-growing province. Combination vehicles longer than 25 m are generally not permitted.
