Canada is warming at two to three times the global average, putting vital infrastructure, such as bridges, at risk. To help address this, CSA Group released the 13th edition of the Canadian Highway Bridge Design Code.
CSA S6:25, Canadian Highway Bridge Design Code, the 13th edition of the code, is the first to use predictive modelling to account for future climate change risks, establishing a consistent national direction to help extend bridge lifespans and reduce repair costs.
By establishing a clear national standard, CSA S6:25, Canadian Highway Bridge Design Code equips engineers to build bridges that are not only safer and more reliable today, but also more resilient to the climate realities of tomorrow.
