Let us show you a cost-effective way for crossing small streams.
Our professionally engineered, pre-stress-laminated timber bridges are certified to carry a maximum load of 80,000 pounds. They’re designed to meet American Association of State Highway Transportation Officials (AASHTO HS-20-44) Specifications.
Our bridges are made from CCA-treated lumber encased in steel channel. Our patented Shear Key design allows each bridge to operate as a single, solid structure with weight distributed evenly across the entire bridge. Each bridge is designed for fast, easy installation with a dozer, excavator or boom truck.
Our timber bridge systems help meet and exceed Best Management Practices for stream crossings by minimizing stream siltation and erosion during installation, use, and removal of the bridge.
Our stress-laminated timber bridge systems meet the requirements of Virginia Department of Environmental Quality (DEQ) Specification 3.24. They’ve been used for flood relief, temporary crossings into wetlands to perform studies, and for initial access for performing evaluations for housing development projects. Several departments of the West Virginia Division of Highways have approved the structures as overlays on weight restricted DOH bridges. We’ve provided bridges to New York State for access throughout the Hudson Bay Watershed, and the spans have been heavily used in the timber and oil and gas industries. Some have been installed for permanent access to parks, recreation areas, and private lands.
Our timber bridge systems help drillers and loggers meet and exceed Best Management Practices for stream crossings by minimizing stream siltation and erosion after the job is done. They also help keep debris out of the waterway, with no in-stream construction. They’re widely used on larger farms, and for housing developments and personal home sites. Bridges are:
