Precast Box Culverts by Sherman-Dixie

Precast Reinforced Concrete Box Culverts & Aqua Arch 3-Sided Culvert

Uses
Precast Concrete Box Culverts can function as a structure, a conduit or both! They are recommended for applications where circular concrete pipe cannot provide adequate flow capacity. Precast Boxes are a superior substitute for cast-in-place box culverts, long-span metal arches, short bridges and multibarrel circular culverts.
