Dangerous Potholes on B.C.'s Coquihalla Highway: Drivers Warn of Bathtub-Sized Hazards (2026)

Drivers are deeply concerned about the alarming size of potholes on British Columbia's Coquihalla Highway, with some being compared to small bathtubs. This issue has raised serious safety concerns among motorists, as highlighted by a concerned woman from Kamloops, B.C., who fears that someone might suffer fatal consequences after colliding with one of these enormous potholes.

But here's where it gets controversial: it's not just her expressing anxiety over these hazardous road conditions; many others, including long-haul truck drivers, are raising their voices about the perilous state of Highway 5, which connects the Lower Mainland with the southern part of the province.

On January 10, Kari-Anne Flatmark experienced a tire blowout after hitting one of these sizeable potholes near Hope, B.C. Just moments before her incident, she had seen another driver stranded on the roadside, changing a tire due to similar damage. "When I refer to potholes, I'm not talking about minor ones," Flatmark recounted in an interview with CBC's Daybreak Kamloops. "We're dealing with enormous holes... It felt like we were shot at with the loudest bang imaginable."

At the time of the impact, she was traveling at 100 km/h, and although both she and her daughter emerged unscathed, the financial burden was significant—flat out around $1,000 for tire replacements and other necessary repairs. "We were fortunate," she remarked, adding, "I genuinely believe that someone will lose control after hitting one of these potholes."

Dave Duncan, the manager at Yellowhead Road and Bridge, noted that two of the potholes are indeed comparable in size to a "small bathtub." His company oversees maintenance along a 140-kilometer stretch of the Coquihalla, stretching from just northeast of Hope to Lac Le Jeune, located north of Merritt, B.C. Duncan emphasized that addressing potholes is a daily task, revealing that his crews have patched the same problematic areas up to 60 times this winter alone, all due to the relentless freeze-thaw cycles that wreak havoc on the asphalt.

"Even with our best efforts, a pothole can reform every single day," he explained.

Longhaul trucker Harman Sidhu also shared his frustrating experience after encountering a series of potholes on the Coquihalla earlier this month, resulting in tire damage. "There was no warning, no reduced speed sign, nothing," he expressed in an email. "Hitting that pothole felt like colliding with a brick wall... The entire highway is a joke."

At the Kal Tire store in Merritt, the influx of drivers seeking repairs due to pothole damage is noticeable. Assistant manager Jordan Pinto reported that lately, six or seven customers have been arriving each day, many describing potholes measuring eight feet wide and four feet deep. "They're pretty frantic when they get here," he said, noting that this year stands out as unusually problematic compared to previous years.

A blown tire not only results in costly repairs but also poses a significant safety threat, as it can easily lead to loss of vehicle control.

Duncan attributed the ongoing issues to heavy snowfall in certain sections of the Coquihalla since December, followed by melting that creates a destructive freeze-thaw cycle. As temperatures rise, melted snow seeps into cracks in the asphalt, only to freeze again when temperatures drop, causing further damage. "The ice begins to chip away at the asphalt, leading to the formation of potholes. Once they start appearing, they can present a real challenge throughout the winter," he detailed.

To tackle the pothole problem, Duncan stated that his team uses a type of asphalt that is better suited for colder weather. However, he cautioned that winter-grade patches are not as resilient as those applied in summer months. In response to growing concerns, a spokesperson from the Ministry of Transportation and Transit affirmed that contractors are actively monitoring, identifying, and repairing potholes along the Coquihalla Highway. They also reminded drivers to adjust their speeds according to road conditions, especially in light of the prevalent potholes.
