​Relocatio​​n of Fibre Optic Cable - Terwillegar Drive/40 Avenue to Whitemud Drive/56 Avenue 

Beginning this summer, EPCOR will be relocating two fibre optic cables to accommodate the planned City of Edmonton Terwillegar Drive Expansion. This work is planned to be completed in early 2023. ​​​​

Project overview

​This projec​t will ​involve: ​

  • ​Working with the City of Edmonton to install approximately 2.0 kilometres (km) of new conduit, utilizing open trench horizontal directional drilling(HDD) from Terwillegar Drive/40 Avenue to Whitemud Drive/56 Avenue to connect to the existing conduit;
  • EPCOR contractors installing two new sections of fibre optic cables that are approximately 2.3 km long. These cables will run underground through existing and new manholes in the new conduit from Terwillegar Drive/40 Avenue to a cable pull box located on Whitemud Drive/56 Avenue.

The new conduit and fibre optic cables will replace the existing conduit and fibre optic cables planned to be removed for the Terwillegar Drive expansion.

Please see Project Map​ for work locations.

Why this project is nee​​​ded

As part of the City of Edmonton Terwillegar Drive Expansion Project, EPCOR will be installing new sections of fibre optic cables to accommodate the planned Terwillegar Drive expansion.​

Fib​​re optic cables

Fibre optic cables provide an essential communications link between neighbouring substations and EPCOR’s control centre. This enables EPCOR to monitor and remotely control its transmission equipment, communicate with other transmission operators, and ensure the safety and reliability of EPCOR’s transmission system.

Construction impacts

​Hours of Work​​​

Typical hours of construction will be from 7 a.m. to 9 p.m., Monday to Saturday. If required, these hours maybe extended, and construction may occur during overnight times.

Road Closures

Roads where crews are working will be reduced to one lane to provide a safe area for crews to work and space for the necessary equipment. Proper signs and barricades will be put up during these temporary lane closures. 

Temporary Parking Restrictions 

If necessary, temporary No Parking signs will be put up in areas where crews plan to work. Signs will be removed when the work is complete, typically one to two days later. 

Power Outages 

No power outages are anticipated as part of this work.

Construction Noise 

Since most of the new fibre optic cable will be installed underground through existing manholes, construction noise should be less than noise typically associated with heavy construction. 

We will take measures to ensure we comply with the City of Edmonton’s Community Standards Bylaw for Noise Control. If it is necessary to temporarily exceed acceptable noise levels, we will work with the City of Edmonton to obtain the necessary permits. 

Construction Equipment 

This type of work requires the use of various construction vehicles such as: reel trailers, cable winch and hydrovac trucks. 

Work Space 

All work areas will be safe and secure. All construction activities will be in accordance with the City of Edmonton bylaws, Occupational Health & Safety requirements, and EPCOR’s strict health, safety and environment procedures and guidelines.
