Shawn Morency, plow driver, describes clearing Highway 138

It’s been a long few days for Shawn Morency, a plow driver in Kegaska, Que. on the eastern shore.

His crews have been working double time to try to clear up Highway 138 after a massive snow storm battered Canada’s east coast.

The drifts covering the road arethe height of a small building.

At their lowest, 14 feet, or four metres.

At their highest, over 20 feet, or six metres.

The drifts are so high, a single plow can’t get through.

A lead snowblower is attached to a front-end loader, which is raised as high as possible to plow the top part of the drifts.

Then they have to plow the bottom, and then other snowblowers need to go behind them.

And that’s just to clear the snow for one lane, to open Highway 138 in case of emergencies.

Morency said it’s impossible to tell where you’re going in the sea of snow.

“All we see is white,” he said. “You hope you’re still on the road and going the right way.”

He said he hopes Highway 138 re-opens for medical emergencies on Wednesday. He’s not sure when two-way traffic will open again.
