MISSOULA, Mont. - It may not help a chicken cross the road, but it may cut down on some roadkill.

It’s called “critter crawl” and consists of a metal mesh shelf suspended inside a culvert -- to let animals go under the road instead of across it.

It also has a side tube for use by smaller animals like mice.

Four of the shelves are now being used on a busy highway in southwestern Montana. An ecologist says he’s documented animals like weasels, raccoons and house cats using it.
