Pelješac Bridge

The Pelješac bridge is at the time the largest bridge project ongoing in Croatia and one will be one of the largest bridges in Europe. The bridge will connect the Croatian mainland with the Pelješac Peninsula on the Split - Dubrovnik Adriatic coastal Motorway near Komarna. The overall length of the bridge amounts 2404 m, with spans of 84 m + 2 x 108 m + 189.5 m + 5 x 285 m + 189.5 m +2 x 108 m + 84 m.

The bridge is multi-span extradosed cable-stayed bridge with an orthotropic steel deck. The width of the three-cell superstructure is 22.50 m. The pylon heights above the sea level differ from 75.4 m to 90.8 m. The bridge is founded deeply on driven steel piles of diameter 2.0 m, length from 55 m to 125 m. The central part of the bridge will be constructed by balanced cantilever construction method and approach parts will be constructed by incremental launching method. The average sea depth in bay is app. 27 m. Dimensions of navigation channel in central span are 250 m x 55 m.

Ponting prepared preliminary and final design. Ponting also prepared complete CFD (Computational Fluid Dynamic) wind analysis and organized wind-tunnel tests which were performed by Force Technology from Denmark.
