Main/Greenfield Underground Conversion Project

February - March 2024

The City of Ottawa is renewing aging infrastructure and revitalizing the right of way in the northern section of Old Ottawa East. As part of this project, Hydro Ottawa will be upgrading our electricity distribution system.

At the request of the City, Hydro Ottawa will be undergrounding the existing overhead line along Main Street, between Harvey Street and Echo Drive. They have also requested burying Greenfield Avenue between Main Street and Havelock Street. New concrete encased duct structure will be installed under both sidewalks, with new service conduits to each property. This work will be coordinated with the City's contractor and schedule. The City will complete the civil work on Hydro Ottawa’s behalf.

What will this project include 

  • Installation of concrete encased ducts in the roadway
  • Removal of overhead lines and poles
  • Excavation for trench and bedding preparation

Why we are moving forward with this project

This project is in support of the City of Ottawa’s Main/Greenfield Road rehabilitation project. The new underground network will provide greater reliability and protection from weather and other external events that could cause unplanned outages.
