Manufactured in LeRoy, West Virginia
Pre-Engineered • Prefabricated • Made in the USA
Pre-engineered stress-laminated timber bridges, delivered ready to install. Rated up to 80,000 lbs. No crane required. Skip the months of permitting, engineering, and on-site construction.
Traditional bridge construction means months of delays, complex permits, specialized engineering, and heavy equipment you may not have. There's a better way.
Traditional crossings can take weeks or months to engineer and construct. Your crews, equipment, and revenue sit idle waiting for access.
Navigating federal, state, and local stream crossing permits is expensive and time-consuming. Prefabricated bridges dramatically simplify the process.
Custom engineering, site construction, crane mobilization, and specialized labor add up fast. Every week of delay costs you more money.
In-stream construction disturbs riverbeds, erodes banks, and creates compliance exposure. A prefab bridge minimizes site disturbance entirely.
Each bridge ships as two modular deck panels on a standard flatbed. Your crew handles installation with equipment already on site.
Your bridge is pre-engineered and fabricated at our facility in LeRoy, WV. Stress-laminated, steel-reinforced, and load-certified before it ships.
Two deck panels ship stacked on a standard tractor-trailer, FOB our facility. No oversized load permits required.
Unload and position with a backhoe, excavator, or skidder. Slide the panels together, bolt the connections, and attach the curbs. No crane needed.
Drive across the same day. Rated for up to 80,000-lb multi-axle loads. Use it temporarily, relocate it when the job's done, or leave it in place permanently.
The answer is stress lamination — a construction method where dozens of individual timber boards are set on edge, side by side, then compressed together by high-tensile stainless steel rods running through the entire cross-section. The rods are tightened to extreme tension, squeezing the boards so tightly that they behave as a single, unified structural slab.

Seven models across two lengths. Every bridge shares the same proven modular design: two 6'-6" panels, 13-ft assembled width, 12-ft drivable surface, steel channel reinforcement, and a patented shear-key mating system.
Top models meet highway-standard load ratings for full-size dump trucks, heavy equipment, and emergency vehicles.
Remove, transport, and reinstall at a new site. These bridges are built as long-term capital assets, not one-time-use structures.
Kiln-dried after treatment for dimensional stability. Engineered to perform in wet, harsh, and environmentally sensitive conditions.

Every bridge is fabricated at our facility in West Virginia. Stress-laminated timber. Structural steel channel. Load-tested before it ever leaves the shop.
These aren't temporary mats or makeshift crossings. Every bridge is a pre-engineered structural system — #1 Grade southern yellow pine, stress-laminated with high-tensile stainless steel rods, encased in structural steel channel. The result is a unified deck that carries highway-rated loads across spans up to 30 feet.
Whether you need a temporary crossing for a six-month project or a permanent installation for decades of service, we'll help you find the right bridge for the job. Most inquiries get a response within one business day.
