A large bridge is under construction on the Akashi-Kaikyou, and the working areas were set up close to the congested marine traffic route. The authors analyzed the effect of these areas on the traffic flow using the results of the traffic surveys whenever the areas were extended three times. When there was one area on the south side of the route at the first survey, the flow of ships passing inside of the route shifted to north in general for keeping the clearance from this area. When the route was sandwiched between two areas on the second survey and third one, the traffic density on the route much increased by which a number of small vessels restricted by the area flowed into the route. The effect of the areas on the flow occurred around 2-3kms in front of the working area. This values increased due to the expansion of the area. That is about 7 times of the width of the area. Using the observed results, we proposed an index which indicates the variety of ship tracks.
