Evaluation of Wood Species and Preservatives for WisDOT Sign Posts

The Wisconsin Department of Transportation (WisDOT) uses preservative-treated wood posts for much of the signage along state highways because wood is relatively inexpensive, easy to install, and has the necessary strength properties to tolerate typical Wisconsin wind loads. Although WisDOT’s experience with wood sign posts has been generally positive, there are some areas of concern, as well as opportunities for diversifying the wood species and preservatives used. WisDOT and the United States Department of Agriculture, Forest Products Laboratory began a collaborative project to address those concerns and opportunities. This report presents the findings of the comprehensive literature review.
