Construction of first composite arch bridge in Trinidad

Lincoln and Associates used Strongwell’s Composolite Building System to make a corrosion resistant bridge.

ccording to the Federal Highway Administration (FHWA), as of December 2013, there are over 29,000 structurally deficient and functionally obsolete bridges within the National Highway System and over 140,000 outside of the system.

Factors leading to a bridge’s deficiency are usually directly attributed to corrosion. Hybrid composite concrete bridge technology has offered a step-in solution to reduce upfront costs in material, fabrication time, transportation, construction time and maintenance issues from traditional bridges. Advanced Infrastructure Technologies (AIT) offers a 100-year lifespan system which utilizes FRP composite tubes to act as external reinforcements and a permanent formwork for cast-in-place structures to replace steel rebar, eliminating all exposure to rust and corrosion – an $8.3 billion direct cost problem for our nation’s infrastructure, according to a 2002 FHWA study.
