Replacing open steel grid decks that are commonly used in moveable bridges with a low-profile FRP deck can improve rider safety and reduce maintenance costs, while satisfying the strict weight requirement for such bridges. The performance of the new deck system, which includes fatigue, strength, connection to steel girders, and compatibility with a polymer concrete wear surface, was evaluated by full-scale testing in a two-span continuous configuration. The deck has successfully passed the preliminary strength and fatigue tests per AASHTO requirements. It has also demonstrated that it can be quickly installed and that its top plate bonds well with the wear surface.
