Nissibi Euphrates BridgeOverview
The Nissibi Euphrates Bridge is a cable stayed bridge spanning the Lake Atatürk Dam on the Euphrates River at the provincial border of Adıyaman–Siverek in south-east Turkey.
The former bridge was flooded during the construction of the reservoir in 1992. Consequently, the traffic between Adıyaman and Diyarbakır was diverted and a ferry service opened in order to maintain traffic.
As the travel time had to be reduced, the target was to bypass the existing detour by projecting a new bridge. This project also had the aim to shorten the route of about 60 km. The 610 m long cable-stayed bridge opened in May 2015.
mageba supplied 2 units of 23.9 m TENSA-MODULAR expansion joints of type LR10.
These joints accomodate movements in every direction and rotation about every axis. They also form a waterthight system which was invented by mageba several decades ago.
Moreover, a special cover plate design between both bridge decks were installed hence assuring a safe utilisation of the footpath to the pedestrians.
All joints are designed to accomodate movements of a total of 800 mm in longitudinal direction and 300 mm in transversal direction.
