On Alberta’s roadways, it’s not uncommon to see trucks hauling massive industrial equipment, large farming equipment and entire buildings or homes.
While it’s necessary for vehicles of all sizes to be able to navigate our roads, oversized or high load vehicles have the potential to damage street lights or worse yet, make contact with an overhead power line.
Oversized loads are regulated by the Government of Alberta to protect the safety of the public and to avoid damaging infrastructure like power lines. Utilities in both urban and rural areas work with transporters and farmers to ensure high loads can travel safely within our province.
“It’s a big undertaking and a lot of planning goes into ensuring high load vehicles can travel safely around our province, “said Leanne Dawkins, JUST Working Group, ENMAX. “It’s important that anyone transporting a high load around power lines contact the utility early so they can make plans to get crews and equipment scheduled and in some cases schedule a power outage to assist in the move.”
- Plan ahead: Notify your local utility company in advance of transporting, as it may need to shut power off in preparation. Don’t forget to take weather conditions and heavy traffic into consideration when planning.
- Know the height of your equipment: Newer equipment models can reach as high as 5.9 metres. Know the height of each piece of equipment before moving it, as equipment is taller if placed on a trailer. Check that all augers, dump truck beds and other equipment are in the lowered position before transportation.
- Know your route: Power lines can hang as low as four metres from the ground. Keep this in mind as clearance heights are reduced when off major highways.
High Load Vehicle Regulations
Alberta Transportation establishes maximum vehicle weight and dimension limits to preserve highway infrastructure and to ensure the safety of the travelling public. This includes legal limits for any registered vehicle for travel on any public road, as well as the provision for movement of oversize loads under permit.
Alberta also has a High Load Corridor or a network of designated highways in the province which have had the overhead utility lines raised to accommodate loads up to nine metres (29.5 feet).
For more information about regulations for oversize vehicles and to access the High Load Corridor map visit the Government of Alberta website or contact your local utility company.
