Analysis on bridge health inspection results and maintenance work cost records were conducted targeting road bridges in Kanagawa prefecture, which may provide a helpful perspective for estimation of future maintenance cost of bridges. The inspection results of 336 bridges were analyzed by type of structural members and implied tendency so that corrosion in steel girders and cracking in concrete girders and slabs progress relatively slowly but some types of concrete member deteriorations are found after escalation. The maintenance work cost record showed that total cost accumulation for repairing work of concrete bridges occurs rarely but drastically at one time. Besides, in steel bridges total cost accumulation for repairing increases slowly but steadily due to paint deterioration or corrosion.
