High Load Corridor


The High Load Corridor consists of designated highways within the Province of Alberta, which have had the overhead utility lines raised to accommodate loads up to 9.0 metres high unless noted otherwise. The initial corridor construction was funded by the Department, with the cost being recovered from the users of the corridor in the form of permit fees as per the fee table.

This electronic service is meant to be a simplified guide to certain parts of the acts and regulations, and not a substitute for them.

Alberta Transportation, Transport Engineering Branch, is not responsible for any omissions in the following documents. It is the responsibility of the transporter to consult the regulations for the exact requirements before moving shipments.

Proposed Future High Load Corridor


Alberta Transportation is responsible for the long-term planning of the highway network and oversees the network's design, construction, and maintenance activities. In 2018 Alberta Transportation completed a comprehensive province-wide planning study titled ‘High Load Corridor Network for Over-size and Over-weight Loads in Alberta. The purpose of the study was to take a long term, holistic approach for updating and developing Alberta’s High Load Corridor network.
