Abstract: In recent years, the concept of an economical, durable, short-span bridge that reduces construction time has become to the county engineer more of a necessity than a goal. In addition, county engineers are seeking these same qualities in methods to repair and strengthen existing bridges on the secondary road system. This is just one of the goals that the Innovative Bridge Research and Construction (IRBC) Program, sponsored by the Federal Highway Administration (FHWA), wishes to achieve through sponsored research projects. Delaware County, Iowa, took a step in that direction through the construction of a 64-ft-long bridge using glued-laminated timber girders reinforced with fiber-reinforced polymer (FRP) and a transverse glued-laminated timber deck. The bridge was fabricated by Alamco Wood Products, Inc., of Albert Lea, Minnesota. Prior funding for the design, construction (including materials), and monitoring/evaluation of this project has been obtained through the IBRC Program with the assistance of Curtis Monk, Division Bridge Engineer with the Iowa Division of the FHWA.
