Abstract: A culvert system includes a flexible toe wall that connects to and extends down from the bottom of the culvert. The flexible toe wall is capable of readily conforming to various shapes of the trench conditions provided to receive the toe wall, before or as the trench is backfilled.

Abstract: A bridge system uses foundation structures that are formed of the combination of a metal-frame structure and cast-in-place concrete. The metal-frame structure of the foundation is capable of supporting bridge units before pouring of concrete.

Abstract: A corrugated plate structure includes a plurality of corrugated plates connected together to form a corrugated structure having a corrugation direction and a cross-corrugation direction. A reinforcement system includes: a first bracket and a second bracket, where the first bracket extends substantially parallel to the cross-corrugation direction and mounted to side-by-side first and second corrugation crests so as to pass over a corrugation valley that joins the first and second corrugation crest, and where the second bracket is spaced in the corrugation direction from the first bracket, and the second bracket extends substantially parallel to the cross-corrugation direction and mounted to the first and second corrugation crests so as to pass over the corrugation valley. An elongated reinforcing member extends substantially parallel to the corrugation direction and mounted to both the first bracket and the second bracket.
