Box culverts are structures that typically span a shorter distance. They may be pre-cast or cast-in-place.
Pre-cast culverts are fabricated offsite and installed in segments using bolts. Cast-in-place culverts are constructed as one unit, onsite, using forms and reinforced concrete.
Box culverts are a more cost-effective option when stream crossings allow. These structures also require very little maintenance during their life span.
