An economical, lightweight and strong bridge alternative
Frequently used as alternatives to traditional span bridges, open bottom structural plate culvert designs made from AIL’s Bolt-A-Plate offer improved hydraulic flow, help counter erosion and preserve natural streambeds.
Easy to ship and install using local crews and equipment
Bolt-A-Plate structures are attractive alternatives for DOTs, counties and municipalities as they are easy to ship and install using local crews and equipment. The geometries of bolted plate bridges can be easily tailored to site and project requirements. And, with no decking or joints at the road surface, their reduced maintenance and lower life cycle costs are very attractive.
Bolt-A-Plate is recommended for buried bridges and tunnels, grade separations, road or rail underpasses, stream crossings, fish passages, culvert relines, stockpile or escape tunnels, portals, canopies, storage structures, utilidor systems and conveyor covers or overcasts.
