We see in case of Sung Soo Bridge Callapse Disaster that technologies which detect and worn of emergency have not: been developed yet and foreign measuring devices are not suitable for full time safety monitoring. Thus the safety checking of bridges is done regarding limited portions depending on visual inspection in special occasions. In this work we are pursuing 3 year term devepopment project ('95-'97) of new brige safety monitoring system which utilizes a Fiber Optic Strain Senor Cable long (10km) enough to attatched to most of the portions and whole important structure to be checked and, once it detects an abnormal strain, puts out worning signals while displaying its location on its graphic map monitor.
