Moskva River
Smolensky Metro Bridge (, "Metromost") is a steel arch bridge that spans Moskva River in Dorogomilovo District of Moscow, Russia. It is the first bridge built for the Moscow Metro in 1935–1937, designed by N.P.Polikarpov, P.K.Antonov (structural engineering) and Yakovlev brothers (architectural design). It is one of two (the second one is Mitinsky Metro Bridge) bridges over Moskva River that are used exclusively by Metro (subway) trains, while the other Metro bridges combine road and rail.
