UNION GAP, Wash. -- Washington state is recycling old highway signs in Union Gap.

Washington State Department of Transportation uses the same aluminum base and refinishes the signs.

This process helped reuse more than 500,000 square feet of aluminum over the last decade.

Workers say they can crank out 300 to 400 small signs a day, or about 15 to 20 large signs.

Recycling instead of buying replacements saves about $100,000 a year.

Any sign can be recycled as long as it has no dents.
