In 1990, the Virginia Assembly established a commission to propose recommendations to enhance the economic development of the southside region of the Commonwealth. The commission's 1991 report, House Document 42, included a recommendation for a timber bridge initiative to replace Virginia's structurally deficient bridges. The commission noted that timber bridges could save highway construction funds and stimulate the forest products industry in southside Virginia. This report addresses some of the economic issues. The long-term performance, and thus the life cycle cost competitiveness, of timber bridges cannot be determined at this time. However, timber bridges are not economically competitive from a cost standpoint. The economic viability of timber bridges is adversely affected by the lack of an industry presence in Virginia. This lack also casts doubt on the ability of the Virginia timber bridge initiative to enhance the economic development in the southside region of the Commonwealth.

Timber bridges play a critical role at local, state, and national levels. They provide rapid and cost-effective transportation solutions. To that end, this bulletin addresses the benefits of constructing bridges with timber, including low carbon footprint, short construction time, environmentally benign aesthetics, high strength-to-weight ratio, off-site fabrication, extended service life, long spans, and favorable economics. Methods for improving timber bridge durability and protection are critical aspects of this bulletin. Physical, chemical, and design-based protection strategies against biotic organisms and abiotic stressors, methods of protection and maintenance as well as choice of structural form are included in this document. Options for use of hardwood species, treatment techniques, connection details, and deck design are described. Nationally recognized standards, including AWPA, ASTM, and AASHTO are referenced to facilitate knowledge transfer. Examples of timber bridge construction from around the world are illustrated. It is hoped that this bulletin will inspire, promote, and educate many stakeholders, designers, supervisors, and engineers in the field of timber bridges for years to come..
