Arch span, pedestrian walkway and cantilever arches represent monolith structures made of glass and plastic shell with polyurethane foam filler. Glass and plastic shell of arch span and glass and plastic shell of its part in pedestrian walkway, as well as glass and plastic shell of cantilever parts and glass and plastic shell of their part of pedestrian walkway are arranged as a whole when manufactured. Arch span and cantilever beam in cross section have "П"-shaped profile that represents monolithic structure of spaced power beams connected to each other by panel of pedestrian walkway and combined by a single shell. Spaced power beams and panel of pedestrian walkway are additionally connected to each other by transverse glass and plastic diaphragms. Upper part of bridge is equipped with barrier railings.
