KŐRÖSHEGY VIADUCT

The Kőröshegy Viaduct is the longest and highest bridge of Hungary. The 17-span, continuous, prestressed concrete beam bridge was constructed according to the design of Hídépítő Ltd. and Pont-Terv Ltd. The cross-section of the superstructure is a haunched two-cell box section, which carries 2×2 traffic lanes and sidewalks.

The bridge was built partly with the cantilever method, partly with an auxiliary erection bridge lifting the precast elements to their places. Due to the curvature (R=4000m) and the elevation (2.86%) of the bridge special solutions were applied at the design of the bearings and the expansion joints as well.
