Ledcor Constructors

Southwest Calgary Ring Road

The Southwest Calgary Ring Road (SWCRR) is a Ledcor project being built between Highway 8 and Macleod Trail SE in Calgary, Alberta. The project includes reconstruction of Glenmore Trail, between Sarcee Trail and east of 37 Street SW, and consists of the following:

  • 31 kilometres of six-and-eight-lane divided highway
  • 14 interchanges
  • 47 bridges
  • one road flyover
  • one railway crossing (flyover)
  • one culvert set
  • one tunnel
  • three river crossings over the Elbow River and Fish Creek.

As part of Public-Private Partnership model, the design and construction were contracted to KGL Constructors, a joint venture partnership between Kiewit, Graham and Ledcor. Preliminary construction began in the summer of 2016 and major construction followed in the spring of 2017. The southwest portion of the ring road is expected to be open to traffic in 2021.

SWCRR is a part of a national and provincial strategy to create economic trade corridors, which link markets, both inside and out, of Alberta. This project is part of the National Highway System, which provides trade connections from all Alberta communities into inter and intra-provincial major centers, major ports of entry with the United States and a connection to tide water. SWCRR also forms part of the CANAMEX / North South Trade Corridor. In 2017, Alberta exported goods via this corridor that totaled $4.3 billion to the USA and $610 million to Mexico

The challenges of building this project are significant and include minimization of traffic disruption to the public, noise mitigation, fine particulate and silicate mitigation as well as erosion mitigation and associated water control which result from storm events.

It is estimated that daily traffic volume on this project portion of SWCRR will be between 80,000 between 100,000 vehicles per day.
