Structural Plate Bridges & Tunnels

A complete range of structural plate products for buried bridges and other applications.

Big R Bridge has been providing value-engineered structural plate solutions since 1970.

Structural Plate Bridges and Tunnels use proven technology based on soil-structure interaction to share the load. They are also flexible and resilient in less-than-ideal foundation conditions and can accept a variety of backfill materials.

Buried Bridges, in particular, have emerged as a cost-effective and easy-to-build alternative to
traditional bridges and precast options for a wide variety of bridge and multi-cell box
culvert crossings.

Big R Bridge leads the way in working with owners, engineers, and contractors to customize solutions for their site requirements. Our experienced in-house engineering team is also ready to assist with on-site guidance.
