The premier precast concrete arch-box system for bridges, culverts, and underground containment.

Versatile. Durable. Proven.

The ECO-SPAN® system is a proprietary precast concrete solution designed to meet the rigorous demands of modern transportation infrastructure. By combining the structural efficiency of an arch with the ease of precast installation, we provide a product that delivers a 100-year service life with minimal maintenance.

Flexible Span Ranges

Whether your project requires a small stream crossing or a wide highway overpass, ECO-SPAN® scales to fit. Our systems typically range from 12' to 80' spans, with various shapes (arches, boxes, and arch-boxes) to accommodate site-specific vertical clearances.

Preserving the Waterway

Traditional bridge designs often require piers or abutments placed directly in the stream, disrupting local ecosystems and complicating permitting. ECO-SPAN®'s clear-span design avoids this entirely. By spanning the entire waterway, we preserve the natural stream bed and simplify the approval process with environmental agencies.
