High Load Moves

Alberta Transportation has designated several high load corridors in Alberta, which allow for loads up to nine metres tall. Aside from these corridors, most of AltaLink’s transmission lines are designed to accommodate vehicles up to 5.3 metres tall where roads and highways are crossed.

While many crossings do have some extra clearance, vehicles and loads exceeding 5.3 metres tall are considered ‘over height’ in Alberta. This means that if you will be travelling with a load exceeding 5.3 metres tall, you will need to obtain a permit from Alberta Transportation.

As per the Alberta Electrical Utility Code, you will also need to contact AltaLink representatives if the total vehicle and load height exceeds 5.3 metres. AltaLink representatives will work with you to schedule your move and develop a plan to accommodate the high load move within the requirements of the Alberta Electrical Utility Code.

Please be aware that we typically require at least 10 business days notice to schedule a high load move. In addition, if your move requires a transmission line outage, up to 6 week notice may be required.

Please fill out the high load move request form and submit it. You can also contact us at 403-960-6055 regarding high load moves.
