LJB has maintained expertise in bridge design since the inception of the company, designing a variety of superstructure, substructure and foundation types. From major highway and railroad bridges to smaller aesthetically-sensitive pedestrian and bikeway bridges, LJB can design a solution for your unique needs.
Effective bridge design includes managing current capacity and planning for future demands, while providing a safe and durable means of transportation. Our structures have ranged in complexity from no skew to a 60-degree skew, and included curved beams, dog-legged beams and haunched girders. We have performed joint replacement, railing replacement/upgrade, slab replacement, superstructure/substructure repair or partial replacement, superstructure and/or substructure widening and replacement of superstructure.
LJB has recognized experts in the field of composite technology on staff. We designed the first bridge in Ohio that incorporated composites into the design of bridge components. We also designed the first bridge in Ohio that uses carbon fiber composite cables (CFCC) and stainless steel—giving it an anticipated life cycle of more than 100 years.
