TORONTO – CSA Group has announced it has released the first bridge design code in Canada to provide engineers with guidance on designing for future risks of climate change.

According to a release, , is the 13^th edition of the code, but the first edition to use predictive modelling.

“Canada is warming at two to three times the global average, putting vital infrastructure like bridges at greater risk,” it reads. “For decades, bridge designs were based on historic climate data, much of it from the 1960s, under the assumption that conditions would remain stable. , engineers must plan for future realities such as higher temperatures, stronger windstorms, sea level rise and higher river flows.”

Key highlights in the code include:

• Climate-resilient design guidance: A national standard that helps engineers adapt bridge designs to a changing climate.
• Use of predictive climate modelling: Tools to plan proactively for risks such as flooding, ice buildup, and stronger storms.
• Focus on long-term performance: Design approaches intended to extend bridge lifespans, reduce repair costs, and minimize disruptions.

“Bridges are long-term investments in our communities and our economy,” said Dwayne Torrey, director of construction and infrastructure standards at CSA Group, in a statement. “This new code gives engineers the tools they need to design infrastructure that anticipates evolving environmental impacts. By building climate-ready bridges today, we can help keep people safe, goods moving, and communities connected for decades to come.”

The code is available on the .
