Structural Plate Bridges & Tunnels

A full range of corrugated metal structures for buried arch bridge construction and many other applications.

AIL has been value engineering cost-effective structural steel plate solutions for over 55 years. Our high-quality corrugated metal products, engineering excellence and innovative designs are key to delivering the best results for our clients.

We manufacture a complete range of buried arch bridges to handle every bridge construction need and budget — overpasses, stream crossings, culverts and more. Our corrugated metal structures ship and install easily with local crews and equipment. These efficient structures offer many advantages over their concrete equivalents or traditional site-built beam bridges or truss bridges, and they offer a wide range of enhanced aesthetic treatments — inside and out.
