The 960.30 m long viaduct, which is formed by two parallel bridges, carries the motorway over a wide valley, a local road, a creek and a rural road. The bridges of 24 spans are divided into three expansion units of lengths 280.15 + 400.00 + 280.15 m. The bridge decks have different widths. They are assembled of 2.00 m deep precast beams and a 0.225 m deep composite slab. The beams are frame connected with piers´ caps of the shape of an inverted letter T. The caps are supported by pairs of slender columns up to 39.70 m high. The bearings are designed only at the end abutments. The bridges form economical semi‑integral structural systems.
