YUSUFELİ
DAM BRIDGES

The construction of the Yusufeli Dam, the tallest dam in Türkiye, has had a significant impact on the surrounding region, as the release of water necessitated the relocation of nearby settlements.


The construction of the Yusufeli Dam, renowned as the tallest dam in Türkiye, has dramatically transformed the surrounding region. As the dam began operations, the release of water from its reservoir necessitated the relocation of several adjacent settlements, displacing residents and altering the regional demographics. In light of this significant change, comprehensive measures were undertaken to reroute transportation routes that had become submerged beneath the water's surface due to the dam's construction. This strategic decision was vital, not only to ensure the continued safety of travelers but also to facilitate efficient movement of goods and services within the region, thereby supporting the area's economic stability and growth.

Construction Methodology

The Yusufeli Viaduct was originally designed using the "Balanced Cantilever" method, and its infrastructure was partially completed based on this design. However, the construction method had to be altered due to the early commencement of water retention works at the dam. Initially, the center spans, which measured 165 meters, were reduced to 82.5 meters by constructing new center piers. Additionally, the cross-section was changed to a much lighter orthotropic steel type to accommodate these relatively large spans using the "Incremental Launch" method, which eliminated the need for extra temporary piers.


Because the geometry of the structure is partly curved and partly linear, the superstructure was launched separately from the two side piers. As planned, three viaducts were constructed using the “Balanced Cantilever” method. In this technique, essential materials for the superstructure, such as concrete, reinforcing steel, and prestressing tendons, are delivered to the form travelers via tower cranes installed on the rear piers.


- This project was expertly designed using cutting-edge techniques to navigate the unique challenges of the rugged terrain, including the deep valley formations, and impressive bridge spans.

- The project establishes a connection between the Black Sea Region and Eastern Anatolia.

- Pylon heights reaching to 150 meters.

- The distance between Artvin and Ispir has been reduced by 15.5 kilometers.

- It reduced the travel time from Yusufeli to Artvin by 25 minutes.

- Four viaducts were constructed: three using the balanced cantilever method and one utilizing the incremental launching method.
