The city is backing up its response to the first major snowfall of the winter season. Monday's snowfall and high winds had many commuters navigating treacherous driving conditions.

City streets appeared to be in better condition Tuesday morning, with the occasional slick intersection.

In the city's downtown, drivers had difficulty getting any traction and cars spun out of control.

"A Ford F-150 tried to go up. I saw his brakes pretty much just lock and his tires and whoosh, right down the road and went right into the intersection," said bystander Julie Laurie.

Eighty city sanding trucks got into action late Monday night. Crews focused on arterials, bus routes and bridge decks. The city says an extra shift was brought in at 7 p.m. in an effort to deal with the slick conditions.

"There's nothing more we could have done. It's again, I think there's a lot of shock and reaction from drivers, the initial blast of winter," said Bob Dunford, director of roadway maintenance, with the City of Edmonton.

During the afternoon commute, close to 25 crashes had been reported in Edmonton, including five injury collisions.

The city says smaller side streets are addressed only on an as required basis. If the weather conditions don't improve and it stays slippery, sanding crews will look at moving into residential neighbourhoods once all the arterials and bus routes are in good condition.
