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

Benefits of the Aluminum Box Culvert:

• Buried Bridge Structure - Reduces maintenance costs and lowers life cycle costs as there are no bridge deck or joints at the deck/roadway interface.
• Modular Bridge System - Rapid installation results in reduced overall project costs, delays and detours.
• Designed “Site Specific” - Meets your site needs in full compliance with AASHTO, ASTM & AREMA design standards for highway and railway use.
• Easy Site-Adaptability - Flexible layout options to fit within the right-of-way – curve the structure with a stream or adjust for vertical and horizontal clearance requirements.

Lightweight for Easy Installation. Aluminum Structural Plate provides all the advantages of steel MULTI-PLATE and its light weight adds to the ease of installation compared to 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.

Aluminum Structural Plate offers designers and DOT’s unparalleled durability, design strength and speed of construction. The combination of lightweight material and variety of shapes and sizes also makes this product excellent in reline or rehabilitation applications.

Benefits of Aluminum Structural Plate:

Redefining standard bridge design for increased durability. The 15” x 5.5” advanced profile allows designers to convert traditional bridges into more economical buried bridges by clear spanning up to 65’. This corrugation is already widely accepted by AASHTO and the international engineering community.

For the past 80 years, Contech MULTI-PLATE® has been the buried bridge standard. BridgeCor enhances the established performance of 6" x 2" MULTI-PLATE by offering 9 times the stiffness and 3 times the strength. Structural plate has proven its bolted, segmental construction to be economical and easily assembled by local forces. Contech BridgeCor is manufactured with the industry’s best equipment allowing for the longest laying length sheets in the industry.
