Abstract
A beam used for construction, particularly of short- to mid-span bridges. A beam can include flanges extending from a web that are joined to flanges of another beam. When joined two beams form an open internal void. The beams can be manufactured from concrete and include an embedded reinforcement cage. Manufacture of the beams utilizes a formwork that can be filled in a single pour.
