Pentele Bridge (Hungary)

The Pentele Bridge or M8 Danube Bridge is a highway bridge spanning river Danube between Dunavecse and Dunaújváros. Construction was completed on 13 March 2007. The Pentele Bridge got her name after the village Dunapentele (now part of Dunaújváros). The bridge is 1682 m in length and 21 m wide, its main basket handle tied-arch span of 308 m ranks 60th among the longest arch bridge spans. It is part of the planned M8 motorway, connecting M6 motorway on the west and highway 51 on the east bank.

Design and construction
The bridge's full length is 1682 m, of which the approaches make up 1067 m on the right bank (From Dunaújváros) and 300 m on the left, while the main river span is a steel basket handle tied-arch of 308 m 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 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 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.
