Description

The Wisconsin Department of Transportation (WisDOT) administers approximately 11,800 miles (18,990 km) of state highways (WisDOT 2014). WisDOT uses preservative-treated wood posts for much of the signage along these highways because wood is relatively inexpensive, easy to install, and has the necessary strength properties to tolerate typical Wisconsin wind loads. Although WisDOT's experi-ence with wood sign posts has been generally positive, there are some areas of concern, as well as potential opportunities for diversifying the wood species and preservatives used. WisDOT and the USDA Forest Products Laboratory con-ducted a comprehensive literature review to examine those concerns and opportunities.show more
