Appalaches-Maine Interconnection

Work may involve upgrading existing roads and building temporary ones, but always with a view to protecting sensitive environments. For existing roads, Hydro-Québec makes every effort to promote shared and safe use. On private lands, the company negotiates temporary access with the affected owners.

Land clearing consists in felling trees within the right-of-way of the future line and along temporary access roads outside the right-of-way. On private lands, clearing work may be done by contractors or the landowner, to whom the felled timber belongs.

This step involves excavation, filling and leveling. The foundations vary according to the type of tower and the nature of the soil.

There are a number of operations in this step: assembling the towers on the ground and erecting them, and installing insulator strings, conductors and ground wires.

This final step involves cleaning up the worksites, leveling and reshaping the ground, filling ruts, seeding worksites around towers and restoring infrastructure (roads, bridges and culverts, fences, etc.). On private land, Hydro‑Québec conducts a site visit with the landowner to ensure that the restoration work meets their expectations.
