We suggest a new mathematical model for dynamical suspension bridge with energy dependent boundary conditions. The roadway of the bridge is viewed as a long-narrow thin rectangular plate. After reducing the evolution problem corresponding to the model to a variational problem, we show that the original evolution problem admits a unique solution. Moreover, the unique solution is explicitly represented.
