THE IMPORTANCE OF MAINTENANCE IN THE LIFE AND ULTIMATE COST OF HIGHWAY BRIDGES IS EMPHASIZED. THE QUESTION OF BRIDGE ECONOMICS IS LINKED WITH BRIDGE DESIGN. CAREFUL STUDY SHOULD BE MADE BEFORE REDUCING THE PROPORTIONS OF VITAL MEMBERS LEST THE ADVANTAGES IN CONSTRUCTION COSTS BE ONLY THEORETICAL AND ACTUAL LOSS BE SUFFERED BY INCREASED MAINTENANCE COSTS. THE REVIEWER FEELS THAT MULTIPLE OR CONTINUOUS SLAB SPANS OFTEN PROVE ADVANTAGEOUS WHERE HEADROOM IS LIMITED AND SATISFACTORY FOUNDATION MATERIAL IS NEAR THE SURFACE. CONCRETE DECK GIRDERS SUPPORTED BY CONCRETE PILE OR CONCRETE COLUMN BENTS, DEPENDING UPON FOUNDATION CONDITIONS, ARE SUITABLE FOR THE INTERMEDIATE RANGE OF BEAM SPAN LENGTHS. STEEL STRINGERS ON H-COLUMN PILES ARE SUITABLE IN CERTAIN LOCATIONS IF THE THICKNESS OF METAL USED IS SUFFICIENT TO PROVIDE FOR LOSS FROM CORROSION DURING THE SERVICE LIFE EXPECTED. MAINTENANCE OF A WELL DESIGNED AND CONSTRUCTED CONCRETE BRIDGE SHOULD BE CONFINED TO MAINTENANCE OF THE WEARING SURFACE OR PAVEMENT; MAINTENANCE OF A STEEL BRIDGE SHOULD BE CONFINED TO THE MAINTENANCE OF THE PROTECTIVE PAINT COAT AND THE WEARING SURFACE OR PAVEMENT.
