Systems approach for abutments of short-span bridges is presented. Ten different systems have been analyzed in detail with a view toward ease of erection, economy, maintenance, longevity, efficiency, versatility, etc. Reinforced earth, gabions, segmental plank, cellular box, steel bent, driven steel pile bent, concrete bent, stub system, concrete and timber cribbing are reasonable suggestions for short-span bridge abutments. Depending upon the merits and demerits gabions, concrete bent, cellular box, segmental plank and timber cribbing appear to be best suited from the industrialized construction viewpoint.
