The Wyoming Department of Transportation is using a new low-tech “cutting edge” technology to keep winter roads clear: beet juice. Ronda Holwell with WYDOT:
She says that the beet juice they use is a byproduct of sugar, and not the red beet juice many may be imagining. Still, it is an effective way to keep the roads clear, and while it may not be quite as strong as the traditional methods, it doesn't have all the drawbacks, either:
She says like the salt brine, they mix the solution locally and transport the solution to use on roads in Sheridan, Buffalo, and other surrounding communities.
