Southwest Calgary Ring Road

​​Progress continues as the Government of Alberta and its partners work toward construction of the final leg of the Calgary Ring Road.

The completion of the Southwest Calgary Ring Road (from 69 Street SW to Macleod Trail/Highway 2A) requires the relocation of ENMAX infrastructure that is directly impacted by the road construction. The Government of Alberta is working with ENMAX to help with their planning and design processes for relocation.

Distribution Projects

In 2015, ENMAX Power Corporation began construction on an underground distribution duct bank from the new ENMAX No. 35 Substation located near 90 Avenue in South Glenmore Park to ENMAX No. 6 Substation located at 16300 – 37 Street SW.

Current Distribution Projects

Anderson Road SW to 146 Avenue SW (Woodbine and Fish Creek Park)

The majority of the duct bank has been installed from Anderson Road to 146 Avenue SW. The Woodbine off leash dog area and pathway will remain closed to accommodate the remaining construction. Pathway closures will continue to be updated on the City of Calgary Pathway Closures website and on the signs posted along the pathway.

The remaining work is as follows:



Road crossing at 130 Avenue SW


Installing electrical cable in the duct bank system (north and south of 130 Avenue SW)


Road crossing at Anderson Road SW west of the pedestrian bridge

Construction scheduled from August 8 to Mid-October 2017

Road crossing at 37 Street SW (near the 300 block of Woodbriar Place SW)

TBD: waiting on Ministerial Consent and Permits
Road crossing at 37 Street SW (south of Fish Creek Park Bridge)

Restoring the pathway and berm adjacent to 37 Street SW (Community of Woodbine)


Pathway restored and open. The berm remediation is outstanding and is anticipated to take place in August 2017.

Construction cannot proceed prior to the issuance of permits from Alberta Transportation however ENMAX is working with the Alberta Transportation and KGL (the road builder) on prioritizing distribution relocation work to accommodate the road construction timelines. ENMAX’s construction dates will be updated in the above table as they become available.

Underground distribution duct bank

A duct bank is a group of electrical conduits normally embedded in concrete that provide pathways and protection for electrical cables. Once constructed, the underground duct bank will allow ENMAX to replace, upgrade or repair the existing underground cables without excavating the entire length of the lines.
