Super-San & Super-Plate

SUPER-SPAN structures utilize MULTI-PLATE plates and special features that allow for a large family of shapes. With spans up to 50 feet, SUPER-SPAN structures are some of the most widely accepted long-span, corrugated steel bridge structures in the world.

 Large Span & Flexible Design 


MULTI-PLATE structures, consisting of field bolted galvanized steel plates, have a long history of strength, durability and economy. The structures offer high combined live and dead load and are well-suited for deep cover applications.

 Fast, Easy, Low-Cost Installation with Proven Durability 

Aluminum Box Culvert

Aluminum Box Culverts are a practical and cost-effective solution for small bridge replacement.The wide-span, low-rise shapes are lightweight as well a fast and easy to install. Spans to 35 feet.

 Practical, Cost-Effective Solution for Small Bridge Replacement 

Aluminum Structural Plate

Aluminum Structural Plate provides all the advantages of steel MULTI-PLATE and its light weight adds to the ease of installation compared to the other structures. It weighs 1/50 as much as reinforced concrete pipe, reducing assembly and equipment costs and allowing for easy handling of long preassembled structures.

 Lightweight for Easy Installation 

CON/SPAN Bridge Systems

CON/SPAN is a modular, precast concrete arch system designed to provide economical, large volume stormwater detention or infiltration below grade. CON/SPAN’s distinctive arch action which utilizes fast, set-in-place construction, has been optimized, providing the ideal blend of hydraulic efficiency and structural capacity

 Accelerated Bridge Construction World Leading Precast Modular Bridge 

BEBO Bridge

The BEBO Bridge Concrete Arch System is a combination of cast-in-place concrete footings, precast arch elements, headwalls, and wingwalls. The system uses the fundamentals of soil-structure interaction to achieve superior strength and stability. It results in as the largest precast arch spans in the world.
