Prefabricated Steel Bridge Kits

Roadrunner Bridge is proud to introduce our patent-pending prefabricated steel bridge kits — our most cost-efficient bridge solution yet. Designed for easy, bolt-together assembly by the end user at the installation site, these kits offer a practical and affordable way to bridge gaps on your property.

Each kit includes 20-foot-long sections available in either 8- or 10-foot widths. For larger spans, multiple sections can be connected lengthwise, with adjustable leg kits providing support every 20 feet to ensure stability over creeks or low-lying areas.

Crafted with an engineered steel frame and fully powder-coated for long-lasting protection, our bridge kits are shipped disassembled for convenience. All components can be assembled using standard hand tools, and even the heaviest pieces are manageable by hand with just two installers.

Buddy Pilgrim stands in front of a wooded landscape and creek as he gives a testimonial about his Roadrunner Bridge.
