ABSTRACT:
A low headroom culvert is provided wherein a series of shallow arch-shaped flat metallic sections are overlappingly secured together. Torsion and buckle resistant reinforcing cross ribbing elements are affixed to the exterior culvert sections at selected points along the culvert to form girder-like beams. The improved culvert structure provides reduced hydraulic flow resistance, can be easily installed and requires less metal for its manufacture in comparison to culverts made of corrugated sheet.
