Design and Construction
The bridge's full length is 1,682 m (5,518 ft), of which the approaches make up 1,067 m (3,501 ft) on the right bank (From Dunaújváros) and 300 m (980 ft) on the left, while the main river span is a steel basket handle tied-arch of 308 m (1,010 ft) length. The river bridge's superstructure rests on two reinforced concrete pillars in the river bed, the right approach is supported by 14, the left one by 5 pillars. The deck is 40.94 m (134.3 ft) wide and carries 2×2 road lanes (3.75 m), 2×1 stopping lanes (3.5 m) a 3.6 m-wide separating line, and on both sides, a 2.4 m-wide pedestrian and bike path. The river bridge is 50 m (160 ft) high, and weighs about 8600 tonnes with all the structures excluding pavement. The arches rise 47.6 meters above the carriageway and are tilted inwards at an angle of 16.5° from vertical resembling a basket handle. The suspension cables run parallel, in the plane of the arches.
The main section of the bridge was assembled on the shore and floated in place using 8 barges of 1600 ton capacity each.
