Availability: Find a library where document is available Abstract: Minnesota contains approximately 2,000 timber bridges, many built in the 1950s and 1960s. Traditional inspection techniques—such as visual inspection, sounding with a hammer, and coring—often miss early-stage or internal damage in timber bridges. This article describes a research project initiated to identify innovative inspection techniques that would enable local engineers to address timber bridge deterioration and extend bridge life. The project goals were to: (1) Identify state-of-the-art nondestructive evaluation (NDE) techniques and equipment for inspecting timber bridges, (2) Develop inspection protocols and procedures for entering the information into Minnesota’s Structure Information Management System (SIMS), (3) Develop an inspection manual for timber bridges, and (4) Train local and state bridge safety inspectors and engineers in each Minnesota Department of Transportation district.
