High flying action above Deerfoot Trail

/ Calgary

Media are invited to get footage of a rare event. On Friday, February 8, traffic will be briefly shut down on Deerfoot Trail at 22x as critical work is undertaken towards the completion of a new substation and transmission line to connect the facility. Substation 54 will enhance power reliability to the new South Health Campus while meeting the growing demand for electricity in Auburn Bay, Cranston, and other southeastern Calgary communities.

Beginning at approximately 10 a.m. until no later than 3 p.m., Deerfoot Trail will be shut down in both directions for maximum five-minute intervals.

During the road closures, a helicopter will lift ropes over the roadway and between two transmission towers positioned on the east and west side respectively. Ground crews will then attach transmission cables to the ropes, pulling them through loops to ultimately connect the two towers. Over the coming weeks, transmission work will continue southbound along the west side of Deerfoot Trail, leading to Substation 54 which is located beside the Pine Creek Waste Water Treatment Facility.

The transmission towers are 23 metres high and the helicopter will hover approximately 15 metres above the peak.



The helicopter will pass over Deerfoot Trail a total of seven times. Police and construction workers will stop traffic each time a pass is imminent. Once the pass is complete, the lanes will be re-opened until the cycle begins again. Speed limits are 50 km/h.

Each full closure will last a maximum of five minutes.
