Power pole fires and downed lines kept firefighters and Enmax crews busy all over Calgary for the last two days.

The effects of freezing rain, high humidity and fog combined with road salt on power lines caused short circuits, which officials say then sparked pole fires Wednesday and Thursday.

Roughly 16,000 people in the communities of Edgemont, Ramsay, Inglewood, East Village, Bridgeland, Riverside, Temple, Westwinds, Saddle Ridge, Horizon and the airport area were affected. Traffic lights were knocked out at intersections all over the city, officials said.

Power has since been restored to all areas, according to ENMAX spokeswoman Doris Kaufmann Woodcock.

Extra Enmax crews were called in and scheduled maintenance was cancelled so workers could focus on restoring power, she said.

"Depending on the amount of damage from the pole fire itself, in some cases those poles need to be replaced entirely, so you can imagine that obviously takes a little bit longer."

Freezing rain makes for slippery commute

Freezing rain overnight also created very icy driving conditions around the city on Thursday morning.

Police said there were 11 injury collisions and many more non-injury crashes.

The major power outage also left many parts of northwest Calgary in the dark on Wednesday afternoon.

Fire officials are reminding people to never touch downed power lines.
