In this paper the conceptual design and technology of construction of a steel orthotropic 90 m long bridge in Sofia, Bulgaria is presented. The steel bridge is part of a multi-span reinforced concrete (R/C) bridge with a total length of 2114 m, a total width of 21.5 m and an average height above the ground of about 10 m. In transverse direction the orthotropic bridge is built with two individual parallel triple-box decks for two-way traffic. Each deck has a 7.5 m wide roadway with two lanes. The bridge is analysed as a frame structure using the finite element method. The design parameters of the bridge are verified by static and dynamic tests.
