The bridge consists of 11 spans, cast-in-place reinforced concrete single solid spine with cantilevers. The span length varies between 9 m and 20 m. The structure consists of a north ramp and a main bridge separated by expansion joints. The north ramp is a three span, constant depth structure spanning the length of 32 m in the east-west direction. These spans are 9 m, 14 m and 9 m. The girder depth is 0,7 m. The total length of the main bridge is 122 m.
