In this paper a study of wind barrier efficiency in terms of traffic safety is analyzed. A novel approach to bridge structures design is represented, where relevant traffic safety issues are incorporated into an early stage of design procedures. The numerical procedure based on standard turbulence model is applied to calculate resulting wind forces on the vehicle of arbitrary geometry. The effect of wind barriers geometry placed on both sides of the viaduct on resulting vehicle wind forces is analyzed. Used numerical procedure has also been experimentally verified in a wind tunnel laboratory. Complex multibody models that could be used to analyze vehicle handling and riding dynamic are represented. Further, vehicle models are used to show how resulting wind forces could affect vehicle dynamic and traffic safety issues. Relevant traffic safety situations are considered and discussed for particular wind barrier.Peer-reviewed by international experts and accepted for publication by SEI Editorial Board

<p> A fixed link between all parts of Croatian territory will be established after completion of the Mainland–Pelješac Peninsula Bridge over a navigable sea strait, with minimum required navigation clearance of 200x55m. The bridge is located in the high-activity seismic zone with design ground acceleration<i>a</i>g=0,41<i>g</i>, strong winds and extremely adverse foundation soil conditions. The original main design of the bridge was completed and building permit was obtained. The construction of the bridge began in 2007, but it was slowed down and finally stopped in 2012 due to financial problems. Two alternative bridge solutions were proposed in the new preliminary design, a continuous steel beam bridge and a multi-span extradosed semi-integral bridge with hybrid deck. After a short account of the original bridge design, both preliminary designs are described in the paper. The</p><p> multi-span extradosed semi-integral bridge with hybrid deck was chosen for further design.</p>

The 2 404 m long Pelješac Bridge, Croatia ranks among the most demanding bridges in the Europe in terms of both the technological complexity of construction and the complexity of the design. The bridge is designed as a multi-span cable-stayed bridge with a semi-integral hybrid structure. While Part 1 (Bauingenieur 5/2023) dealt with the concept and planning of the bridge, the construction and assembly is reported now.

The 2 404 m long Pelješac Bridge, Croatia, ranks among the most demanding bridges in the Europe in terms of both the technological complexity of construction and the complexity of the design. The bridge is located in an area of very high seismic activity, exposed to strong and gusty north and south winds. The compact bedrock is located at a depth of up to 100 m below the seabed so very demanding foundation on up to 128 m long driven steel piles was required. The bridge is designed as a multi-span cable-stayed bridge with a semi-integral hybrid structure with five 285 m long central spans. Part 2 deals with execution and assembly.

<p>The 2404 m long Pelješac Bridge ranks among the most demanding bridges in the world in terms of both the technological complexity of construction and the complexity of the design. The bridge is located in an area of extremely high seismic activity, exposed to strong and gusty north and south winds. It is designed as a multi-span extradosed bridge with a semi-integral hybrid structure with five 285 m long central spans. Once built, the bridge will rank among the 5 largest and most attractive European bridges built in the early 21st century.</p>
