Long-Term Performance of Timber Bridges
Timber bridges are a viable option for the U.S. highway system, mainly along secondary roadways in rural areas. This project will evaluate the long-term performance of timber highway bridges in the United States.
The key project objective is to acquire precise data on the performance of timber highway bridges in the United States. A better understanding of the durability characteristics of timber bridge systems and components will improve comparisons to alternative bridge materials, improve bridge design details and practices, and provide for improvement in extension of service life. The primary objective of this study is to assess the condition and performance of a select number of existing timber highway bridges in various climatic regions in the United States and establish a baseline for evaluating future performance.
