Have you ever had to swerve or have hit an animal trying to cross a highway? What a tragedy for all. Protecting wildlife crossing highways benefits all involved.
Underpasses or overpasses were introduced in Canada years ago to aid in these crossings.
The picture above is an over pass that was constructed on the Trans Canada highway leading into Banff, Alberta. The material used was corrugated plate. Why? Cost savings, speed on installation, resilient, versatile, sustainability and durability.
