FERGUS FALLS, Minn. Those glass bottles that get chucked into the recycling bins? In the not-too-distant future, Otter Tail residents may be driving over them.

The glass will be used below the road surface in an aggregate that forms the road base, and will be covered by asphalt.

“The goal is to build it this year,” Fjestad told commissioners.
