UK Pedestrian Bridge

Palmer Engineering provided structural design services to the University of Kentucky for two pedestrian bridges associated with a new parking structure. One bridge was a single-span structure that carries pedestrian traffic from the garage to another university facility. The second bridge was a multi-span structure that carries pedestrians over Limestone Street.

The structures utilized two precast prestressed concrete type III I-beams in the cross-section. This design proved to be a challenge because the beams over Limestone cantilever past the support pier positioned away from the garage. The cantilever was an effective solution that allowed the foundations of the garage and bridge to remain independent. The design required unusual strand configurations to accommodate the stresses produced in the cantilevers.
