Beltline Downtown Utility Relocation Project (Third-party Shallow Utilities)

The Beltline Downtown Utility Relocation program involving third-party shallow utilities (fibre, electricity, gas, etc.) began in September 2022 and will continue through to spring of 2025. This work is being completed by various third-party utility companies, including ENMAX, TELUS, Bell, Zayo, Calgary District Heating, Rogers/Shaw and ATCO Gas.

Start Date: September 2020
Completion Date: Spring 2025

Prior to tunnelling and building the stations, we must remove potential utility conflicts, which involves moving the existing underground utilities to other locations. By doing this work now, it makes the tunnelling process quicker and reduces risk to the project.

All shallow utility work, which consists of utilities less than 1.5 metres deep, must be completed by the third-party utility company, as set out in The City of Calgary’s Municipal Rights-of-Way Bylaw.

This work is happening across downtown along the entire Green Line alignment, from Eau Claire south along 2 Street S.E. to 11 Avenue S.E. and then east along 11 Avenue S.E. into Victoria Park.

Underneath the streets of downtown Calgary are all kinds of utility lines, such as water, natural gas, and electricity. Before we can build the Green Line tunnel under the Beltline and Downtown, we need to relocate existing underground utilities.

This is a significant investment in infrastructure renewal. New relocated utilities will be built to accommodate increases in population expected in this area in the future. Upgrades in infrastructure will include:

• 1,280 metres of new watermains in Beltline East
• 1,000 metres of new sanitary pipe in Beltline East
• 855 metres of new road
• 670 metres of sidewalk improvements
• 515 metres of new pathway
