Understanding Weight Limits: Protecting Our Roads and Bridges
A Reminder for All Road Users
To ensure safety and preserve our roads and bridges, all vehicles, whether it’s a delivery truck, family car, or agricultural equipment must comply with the posted allowable weight limits. These limits are set to protect our infrastructure and keep travel smooth for everyone.
You’ll find weight restriction signs in advance of affected bridges—typically at the nearest intersection, in advance of the bridge, and at the bridge itself. These restrictions aren’t random; they’re established by qualified Bridge Inspectors based on the age and condition of the structure. For instance, passenger vehicles and light-duty trucks usually fall well below the limits, while heavy-duty trucks or trailers might need to check the signs more carefully. Similarly, agricultural equipment like combines and tractors often fall under the CS1, or “single truck unit” classification, shown as a “truck with no trailer” on the signage. The number beside each classification indicates the maximum allowable gross weight of the vehicle classification.
For more information on safely transporting agricultural equipment on public roadways, restricted bridge classifications, or for a detailed list of restricted bridge locations, visit the Government of Alberta website: https://www.alberta.ca/road-restrictions-and-bans-overview. By working together—whether you’re hauling hay or heading on a road trip—we can all help protect our roads and bridges for years to come.
Drive safe and stay mindful out there!
