A right-of-way is a cleared corridor that runs beneath a transmission line. To ensure safety and service reliability, Hydro-Québec makes sure these corridors remain clear at all times and that vegetation does not grow too close to the lines.
Beneath power transmission lines is a strip of cleared land called a right-of-way. For reasons of safety and service reliability, there are no buildings or trees in the right-of-way. This video explains why and how Hydro-Québec makes sure transmission line rights-of-way are always clear.
