  • Share

Ward 11 official websiteAlberta Transportation has started planning for the construction of the SW portion of the Calgary Ring Road (SWCRR) that will complete the Calgary Ring Road. The completion of the SWCRR requires the relocation of several ENMAX utilities that are directly impacted by the road construction.

Southland Leisure Centre - Pool Viewing Area


Substation Relocation

ENMAX is moving an ENMAX substation, that was approved in May, to accommodate the construction of the Ring Road. The new location of the ENMAX Substation 35 is in the SW corner of South Glenmore Park, just north of 90th Avenue SW on the edge of the 37th street alignment.

To accommodate this new substation, ENMAX is required to relocate underground distribution lines and are constructing 2.3 km of underground concrete duct bank from 90th Ave SW to Southland Drive SW.  Distribution cables will not be run through these duct banks until 2017.

The construction will take place in three sections along the existing pathway during the summer and fall in 2015 and 2016. The construction sites will move south as each piece is completed. Site remediation will begin in the spring of 2016.

Transmission Line Relocation

Alberta Transportation has requested ENMAX to relocate its transmission lines away from the road alignment and into the new Power Line Component of the newly established Transportation Utility Corridor (TUC) along the SWCRR.
This project requires construction of new 138 kV transmission lines as well as the removal and salvage of exisitng transmission lines. The proposed single circuit transmission structures will be self-supporting expandable steel monopoles with a height of 18 to 24 metres. The transmission line running east west to connect to Substation 35 at 90 Avenue SW will be a double circuit line ranging in height from 22 to 27 metres. Distance between structures will be approximately 100 to 140 metres.
The construction is expected to begin in June 2016 with a proposed in-service date of September 2017.
