Advanced Infrastructure Technologies has developed a proprietary composite arch tube system for bridge construction as a more cost-efficient and durable alternative to traditional building methods. Their system uses inflatable composite tubes that are bent on-site to form arches which are then filled with concrete. This eliminates the need for heavy transportation, rebar, and temporary formwork. They have completed the first bridge using this system in Pittsfield, ME and have a pipeline of 16 future bridge projects. Management aims to address the large problem of deficient bridges in the U.S. infrastructure through lower lifecycle costs and a more resilient design.
