Several public bridge projects across the country won recognition in the 2004–2005 Timber Bridge Awards. The awards—sponsored by the American Institute of Timber Construction, the Engineered Wood Association, and the U.S. Department of Agriculture Forest Service's Wood in Transportation Program—are designed to bring attention to the benefits of using timber in bridge construction.
