Alaska Highway Shut Down Near U.S. Border
One of Canada's most iconic and remote roadways is temporarily out of commission after flooding forced the closure of the Alaska Highway between Beaver Creek Canada Customs and the U.S. border in the Yukon.
The closure, which cuts off a key land crossing between Canada and the United States, has left travellers, commercial truckers, and locals scrambling to find alternatives or wait out the repairs. Crews have been deployed to assess and address the flooding damage, though a timeline for reopening has not yet been confirmed.
A Lifeline Highway Underwater
The Alaska Highway — also known as the ALCAN Highway — stretches roughly 2,400 kilometres from Dawson Creek, British Columbia, all the way to Delta Junction, Alaska. Built during World War II as a military supply route, it remains a vital artery for remote Yukon and northwestern B.C. communities that have limited road access to the rest of the country.
For many residents in the region, the highway isn't just a convenience — it's the only road in and out. Flooding events like this one can quickly isolate entire communities, cutting off supply chains, emergency services, and everyday travel.
Spring Flooding a Recurring Challenge in the North
Spring is typically the most vulnerable season for northern Canadian highways. As snowpack melts rapidly across the Yukon and sub-Arctic regions, rivers and drainage systems can overflow quickly, undermining road surfaces and washing out shoulders with little warning.
Transportation officials and local governments in the Yukon have long dealt with the challenge of maintaining infrastructure in an environment where freeze-thaw cycles, permafrost, and heavy spring runoff combine to create recurring hazards. Climate change has added further unpredictability, with warmer springs accelerating melt and increasing the intensity of flooding events across the North.
What Travellers Should Know
Anyone planning to travel the Alaska Highway near the Yukon-Alaska border is strongly advised to check road conditions with the Yukon 511 road conditions service before heading out. The closure affects cross-border movement at the Beaver Creek port of entry, which is the main land crossing for travellers heading into or out of Alaska via Canada in this corridor.
Commercial carriers and freight operators moving goods between Alaska and the rest of Canada will also need to monitor the situation closely, as extended closures can have downstream effects on supply availability in Alaska's interior.
Repairs Underway
Road crews have been mobilized to tackle the flooding and carry out any necessary repairs to the highway surface and drainage infrastructure. The Yukon government has not yet provided an estimated reopening date, but officials are working to restore access as quickly and safely as possible.
CBC North and Yukon 511 are expected to provide ongoing updates as conditions evolve.
