Easy to ship and install using local crews and equipment
Bolt-A-Plate buried bridge structures are attractive alternatives for DOTs, counties and municipalities as they are easy to ship and install using local crews and equipment. Their geometries 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.
