Department of Highways
DHPW
Yukon • Canada
The Yukon Department of Highways and Public Works manages approximately 4,800 kilometers of territorial roads and highways in one of Canada's most remote and geographically challenging territories. The Alaska Highway (Highway 1) — originally built by the US Army during World War II — is the primary freight artery connecting the Yukon to British Columbia and ultimately to the rest of North America. Other key routes include the Klondike Highway (Highway 2) and the Campbell Highway (Highway 4). Commercial trucking in the Yukon faces extreme cold weather challenges, with temperatures regularly reaching -40°C. The department administers commercial vehicle regulations, provides 511Yukon for road conditions, and coordinates with Alaska DOT&PF for the critical Alaska Highway corridor.

Seasonal Restrictions Apr, May, Jun
Spring breakup (April through June) causes road closures and severe weight restrictions across the Yukon highway network. Many secondary roads close entirely during spring breakup. The Alaska Highway (Hwy 1), Robert Campbell Highway (Hwy 4), and Klondike Highway (Hwy 2) are all subject to seasonal weight restrictions and frost damage.

Notable Rules
The Alaska Highway (Hwy 1) is the primary north-south commercial corridor through Yukon, connecting British Columbia to Alaska. Many bridges on secondary highways have low individual load limits. Tandem axle limit of 17,100 kg is below the CCMTA standard. The mining industry (gold, lead-zinc) generates heavy haul traffic, particularly near Whitehorse and Dawson City. Winter temperatures to −50°C can affect equipment performance and road conditions.
