Upcoming EPCOR Construction – MacKenzie Ravine Trestle Rehabilitation Project

March 30, 2021


Good morning,

I’d like to introduce myself – I’m Dawn Fenske, Senior Advisor, Communications with the Drainage Services team at EPCOR. I am reaching out regarding some upcoming EPCOR Drainage construction in your area.


EPCOR is responsible for the maintenance of the main sewer lines and associated infrastructure in Edmonton. As infrastructure ages, it can deteriorate in many different ways. The trestle located in the MacKenzie Ravine has been identified as requiring rehabilitation. The trestle is a bridge constructed out of steel to support a suspended sanitary sewer pipe across MacKenzie Ravine.


EPCOR will be rehabilitating the trestle by replacing and repairing broken steel sections of the structure. This work will occur in two phases:


  • Phase 1 – Removal/trimming of trees and vegetation – March/April 2021

Before construction can begin, a survey of the work area and steel structure is required to help determine the construction plan. To prepare for the survey, smaller vegetation, such as bushes and small saplings, will be removed/trimmed along the length of the trestle and is scheduled to begin on March 29, 2021 and is expected to be completed by April 15, 2021, weather permitting.

  • Phase 2 – Structural repairs to the trestle structure and fencing – anticipated to start in summer/fall 2021

Scaffolding and other supporting structures will be built to support the trestle while the broken sections are removed and replaced. The trestle will be repainted and the existing fences at each end of the trestle will be replaced. Structural repairs are anticipated to begin in summer/fall 2021 and are expected to be completed by end of December 2021.


These timelines are estimates and may change based on weather and construction conditions.


Attached is the project notice that will be delivered to residents in adjacent to the work area. We would like to request your assistance with sharing this information on our behalf.


If you have any questions, please don’t hesitate to contact me.


Thank you,
