The bridge portal has two wind power installations located on it, whose masts (1,2) are connected in force-transmitting fashion by a carrier (3) provided with solar aggregates so that the plant in the wind/solar hybrid system communicates work-wise with storage apparatus for bridge lighting (5) and railway heating (6). The construction of the portal forms a unit separate from the bridge construction and can be added on afterwards. Wind power plants and carriers form a unit architecturally and blend harmoniously into the landscape.
