ABSTRACT
ABSTRACT: There are over one-hundred-and-forty-thousand road bridges with a span of 15 meters or longer in Japan, and about 35% of them were built within the high growth period of 1960’s and 1970’s and the aging of the road bridges will be one of the problems for the road administrators in the near future. Since more than 75% of the total number of bridges are managed by the local governments, authors have challenged to develop a Bridge Management System (BMS) which can be used by many local governments in common.
