It is an exceptional bridge in every respect. With a length of L=2404 m, the bridge is one of the most demanding bridges in the world, both from the point of view of the project's complexity and demanding and complex execution. The concept of the bridge is structurally inventive. It is an integral hybrid construction with a hybrid span construction. The base segments are concrete, and the rest is a steel crates. The suspended span structure and the pylons are elastically fastened to the columns so that the bridge in the central part (75%) of the total length is a frame structure without bearings (good for earthquakes and wind). The bridge location is in an area of high seismic activity. According to current norms, the bridge classifies in the highest importance class IV and bridge type C, which means that it is a bridge of exceptional importance for maintaining communication even after an earthquake, with a service life of >= 100 years. The peak acceleration of the foundation soil is amax=0.34 g, i.e. the required calculated acceleration of Eamax=0.54 g. (Zagreb M 5.5 amax=0.22 g). The compact load-bearing rock is located more than 80 m from the seabed, so including the average sea depth of 27 m, it requires a deep foundation on driven steel piles up to 130 m long (belt tube-cathedral tower). Also, the bridge is in an area of intense and gusty winds with peak wind speeds exceeding 180 km/h. The calculation was made by simulation using Computational Fluid Dynamics and confirmed by model testing in a wind tunnel. The Pelješac bridge is a suspension (extrados) with six pylons and five openings. The total length of the bridge is 2404 m, and it has a total of 13 spans (2x84m, 4x108m, 2x189.5m, 5x285m), the height of the pylon is 98 m, and its width is 22.5 m.
