There are special requirements concerning bridges servicing high-velocity transport. Single track single span railway steel truss viaduct of 93 m theoretical length was tested and numerically analysed. The aim was to assess its applicability to transport of 300/350 km/h velocity and set the basis for its modernization design. The key role played dynamic tests and computations. Their results are presented In the paper. The test and computation results proved that the structure in concern may be adapted to transport of velocity up to 350 km/h. Design computations of modernization should be completed with dynamic analysis under actual loading meant to run on the viaduct.
