Abstract
A bridge is assembled by locking truss-like girders along the sides of a bridge section to the transverse beams by a bayonet-type coupling and a swinging of the trusses relative to the transverse beams. Roadway plates are supported by the transverse beams and additional sections are assembled onto the previous sections. The sections can be advanced across an obstruction on a pair of support beams guided through roller frames affixed to at least the first and last sections, which support beams can later be mounted on the bridge span to function as guardrails.
