Why Are The Roads So Bumpy In The Metro?

MINNEAPOLIS (WCCO) -- Officials with the Minnesota Department of Transportation say that bumpy "wash board" effect on metro roads is caused by a number of factors.

Kent Barnard said they put down "salt brine" to keep the snow and ice from sticking.

"It puts that coating of salt on the roadway and prevents that bonding from snow and ice from forming on the road ways and makes it much easier for us to plow it off," Barnard said.

Barnard said there are a number of factors that go into creating the bumpy roads.

"The warmth is one of them, but the other issue is we had is it was very wet snow, and if it would have been light and flaky, it would have been easier to remove," he said.

The other benefit will be the warmer weather coming up.

"Well, Mother Nature is going to cooperate with us and we are continuing to use mechanical means to get that off so we are hoping that the main lines will be good," he said.

The snow and ice caused major traffic problems again Tuesday morning after the snow storm Sunday.
