Catworks has installed bridges and culverts of various spans and sizes, from over 60 inch diameter culverts to large span, precast deck and girder bridges. These installations comprised numerous and varied conditions and assemblages, including (but not limited to): various abutment designs; stream diversion and restoration; riprap energy dissipaters; aluminized inlets, spillways and splash aprons; and gabion, riprap and cast-in-place headwalls. In addition to traditional culvert work, the nature of our core service areas provides CWC extensive experience installing unique and single design flow management structures.

Bridges

Catworks has performed numerous bridge installation projects, most of them comprising spans longer than 80 feet in length. Our vast experience with bridge construction spans multiple bridge types, including the repair and restoration of the Multnomah Falls Bridge for the US Forest Service; installation of a composite concrete and steel bridges for the US Army Corps of Engineers; and several simple span bridges of varying size and configuration on roads throughout the west coast.

Culverts

CWC has performed construction and installation of a wide variety of culvert structures, including multiple concrete box culverts and open bottom arch multi-plates, many of which required live stream diversions in order to accomplish the work. Notably, CWC constructed an aluminized 171 inch by 110 foot long arch culvert with interior baffle plates and sloped in-and-outlets.
