The Bridge-in-a-Backpack is a lightweight, corrosion resistant system for short to medium span bridge construction using FRP composite arch tubes that act as reinforcement and formwork for cast-in-place concrete. The arches are easily transportable, rapidly deployable and do not require the heavy equipment or large crews needed to handle the weight of traditional construction materials.

Two Maine bridges have been rebuilt using the Bridge-in-a-Backpack technology: the Neal Bridge in Pittsfield, ME (pictured above) and the McGee Bridge in North Anson, ME. Six more of these arch bridges will be constructed in Maine over the next two years.
