Unprecedented storm on Highway 63

The situation on Highway 63 was the result of an extreme and highly unusual spring snowstorm, combined with a series of incidents that quickly escalated into a complex emergency. Over a three-day period, more than 60 centimetres of heavy, wet snow fell, with high winds creating drifts up to four feet deep and near-zero visibility.

It’s important to be clear about what ultimately caused the prolonged closure and the stranding of motorists. The situation escalated when a semi-truck collision blocked multiple lanes near Wandering River in the early hours of April 24. With traffic stopped, blowing snow rapidly created deep drifts across the highway, making it impassable and preventing tow trucks and emergency vehicles from getting through.

From that point on, the priority shifted to life safety — ensuring stranded motorists had support while crews worked to reopen the highway safely.

Our highway maintenance contractors were on the ground throughout this event. Working continuously to plow, sand, and keep routes passable. They brought in additional crews and equipment from surrounding regions and, in many cases, were dealing with conditions so severe that plow trucks themselves became stuck in the drifts.

Despite clear warnings issued well in advance, including “Travel Not Recommended” advisories on Alberta 511, traffic continued to enter the corridor during deteriorating conditions. This created additional pressure on an already strained situation and contributed to the number of vehicles caught in the closure.

Our contractors met and, in many cases, exceeded their contractual requirements during what can only be described as an unprecedented spring weather event. Their focus remained exactly where it should be – keeping as many routes open as possible, supporting emergency response, and preventing the situation from worsening further.

TEC always review major events like this to identify lessons learned and improve future responses. But Albertans should be confident that crews worked around the clock in extremely difficult conditions to protect public safety.

The Regional Municipality of Wood Buffalo and the people of Fort McMurray did a great job stepping up during this incredibly challenging situation. They helped provide resources, coordination, and on-the-ground support to help those affected. This incident is also an important reminder that when severe weather hits and advisories are issued, drivers need to take them seriously.
