In this study, it is aimed to determine the dynamic behavior of steel highway bridge which is subjected to multi-supported excitation effects and supported on different soil types. In this context, Eynel Highway Bridge in Ayvacik district of Samsun is chosen as an example. Ayvacık Eynel Bridge was built in the arch form of a reverse chain curve. The parts of the bridge that were exposed to vehicle loads was made by composite reinforced concrete plates. In the theoretical part of the study, three-dimensional finite element model of the bridge is created by using SAP2000 program. Dynamic analyzes of the bridge are carried out by using the spectrum data obtained depending on the seismicity of the region where it was built. The modal properties of the bridge were determined in conjunction with these analyzes. As a result of analyses in SAP2000 program, it is compared deck displacements effects for all soil types.
