Abstract: 
A change in the ship traffic volume is expected as a result of upgrading of many European waterways. Correlated to improved waterways passage is the increase of ship size and frequency of larger ships. On one hand, the ecological and economic advantages of the upgrading process cannot be disputed, but on the other hand, the changed shipping traffic results in additional risks, especially to bridge substructures. Most of the current bridges were built more than 30 years ago and were generally not dimensioned for horizontal forces expected from large ship impact. Due to the increased capacity and presence of larger ships the bridge substructures are expected to withstand much higher impact loads. These loads can be taken into account in the design of new structures. However, the bulk of existing bridges must be assessed concerning the higher load and if necessary strengthened.
