The paper records some significant and unexpected aspects encountered in bridge testing, so that they could be used in the evaluation of the load carrying capcities of existing bridges. Slab-on-girder bridges are considered as well as steel truss bridges. It is noted that although in most cases the load-carrying capacities of bridges are higher than obtained by the usual calculations, in some cases, the load carrying capacity can be lower than expected. It is therefore necessary to prepare a catalogue of those aspects of bridge behavior that do not usually enter into design consierations and may have significant influence on the ability of the bridge to carry loads. It is shown (by specific examples) that in some cases the bridge behavior may be so deceptive that it can be understood only through a field test.
