INCREMENTAL COSTS OF BRIDGES

CURVES ARE DEVELOPED TO SHOW THE INCREMENTAL COST IN DOLLARS PER SQUARE FOOT FOR THE THREE PREDOMINATE BRIDGE TYPES USED ON WASHINGTON HIGHWAYS, NAMELY CONTINUOUS REINFORCED CONCRETE BOX GIRDERS, PRESTRESSED CONCRETE GIRDERS AND CONTINUOUS REINFORCED CONCRETE SLABS. THE CURVES ALSO SHOW THE COST OF THE THREE BRIDGE TYPES AS PERCENTAGES OF THE COST OF THE DESIGN FOR H20-S16 LOADING. THE INCREMENTAL LIVE LOADS VARIED IN 2000 POUND INCREMENTS FROM A 6000 POUND VEHICLE TO THE MAXIMUM WEIGHT RECOMMENDED BY AASHO. THE CURVES DEVELOPED FOR CONCRETE BOX GIRDERS WILL APPLY SATISFACTORILY TO CONCRETE T-BEAMS AND THE CURVES FOR PRESTRESSED CONCRETE GIRDERS CAN BE USED FOR STEEL GIRDERS. /FHWA/
