Utility relocation


  • Beltline East: Between 6 Street S.E. and 3 Street S.E. between 11 Avenue and 12 Avenue
  • Beltline West: 1 Street S.W. to 1 Street S.E. between 10 Avenue and 12 Avenue.
  • Downtown:  3 Street S.W. to 1 Street S.W., between 7 Avenue S.W. and Riverfront Avenue S.W. (Eau Claire)


  • Construction – January 2022 to 2024


The Beltline and Downtown Utility Relocation project is an advanced works project. It will make way for construction of the Green Line tunnel and stations in Phase 1 from the Elbow River to Bow River.

Work will be prioritized in Beltline east and Downtown. Utility relocations north of Eau Claire are not confirmed.

This work will move shallow and deep embedded utilities in the area including:

  • City sanitary, water and storm water utilities
  • Third-party electricity, gas, phone, cable and fibre optic, internet and other services

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

  • 1280 metres of new watermains in East Beltline
  • 1000 metre of new sanitary pipe in Beltline East
  • 855m of new road
  • 670 metres of sidewalk improvements
  • 515 metres of new pathway

If you own a business in the area above you could be impacted by the Beltline and Downtown utility relocation work and we are here to help.

Project scope and estimated timelines

Beltline East (Culture + Entertainment District)

Estimated timeline: Spring 2022 to 2024

  • Relocate existing deep utility infrastructure (storm and sanitary trunk and water feeder main) from 11 Avenue S.E. and 6 Street S.E. into Olympic Way and 12 Avenue S.E.
  • Replace and upgrade select deep and shallow utility infrastructure in 5 Street S.E. and 6 Street S.E.
  • Relocate/realign existing third-party shallow utilities along 12 Avenue S.E. to facilitate the relocation of major deep utilities into 12 Avenue S.E.
  • In 2022 impacts will include full block closures, intersection closure at Olympic Way and 12 Avenue S.E., cycle track closures, and on-street parking removal

Beltline West

Estimated timeline: Summer 2022 to 2024

  • Relocate/realign existing third party shallow utilities from 11 Avenue S.E. into adjacent streets, avenues and alleyways. This will allow for the construction of the Centre Street underground station.
  • Installing manholes on roadways adjacent to Centre Street Station to allow for its construction.
  • Modifying some building’s third-party utility servicing so the new infrastructure can be connected to buildings on 11 Avenue S.E.
  • Impacts in 2022 will include loss of on-street parking, lane closures on 11 Avenue, 1 Street S.E. and Centre Street.


Estimated timeline: Summer 2022 to 2024

  • Relocate/realign existing third-party shallow utilities from 2 Street S.W. into adjacent roadways
  • Modify some building’s third-party utility servicing so the new infrastructure can be connected to buildings on 2 Street S.W.
  • Deep utility construction in roadways adjacent to 2 Street S.W. This is required to allow future Green Line construction along the 2 Street S.W. corridor between 7 Avenue S.W. and the Bow River.

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.
