Prestressed precast concrete railroad bridges
Historical development and current details of design, fabrication and methods of erection of prestressed, precast hollow concrete box girder units are presented, with special attention to 34 bridges in Los Angeles and San Bernardino counties in California; double-cell box girders form spans to 45 ft, and multiple single cell girders, weighing up to 70 tons each, form spans to 86 ft; epoxy grout joins boxes together longitudinally; upper surface of box serves as floor for railroad-ballasted track section; boxes are supported on elastomeric pads; most economical bridges were 45-ft spans with open-end abutments.
