Abstract: Treated timber bridges have been widely used for railroad and highway bridges throughout the United States during the 20th century. However, improvements in preservative technology are needed as a result of changing environmental views and public perceptions concerning the use of preservative treated wood in aquatic environments. Within the past 15 years, three national programs have been established to advance technologies related to timber transportation structures. A key design aspect for timber highway bridges is the selection of preservative treatment to improve durability while minimizing potential environmental impacts. This paper summarizes timber bridge preservation technology in the United States, including pressure treatment preservatives, field treatments, and remedial techniques.
