This paper describes the validity of the navigation safety assessment for planning the appropriate main-span length for a bridge, using new evaluation index "Potential Collision Risk : PCR" of ship-handling simulation. PCR is the rate of unsafe situation during maneuvering. And unsafe situation is defined as a condition in which the risk becomes obvious in the near future by maintaining the present maneuvering condition unaltered. The main findings of this study are as follows, ・Validity was verified with PCR as a synthetic index in consideration of the maneuverability and other factors. ・PCR is the index that relative comparison is possible with the risk in existent waters. ・There is a correlation between "Potential Collision Risk" and the occurrence rate of accidents classified as sea disasters
