Checking of Final Design of the 2nd Cross-border Road Bridge in the area of the border crossing “Kipi – Ipsala”

Technical Details

The project concerns the new cross-border road bridge “Kipi – Ipsala”, located at the Greek-Turkish border. The bridge is part of the “European Transport Corridor Thessaloniki – Istanbul”, constructed on the frame of the agreement between Greece and Turkey. The bridge superstructure’s width is 34 m and the total length is 841 m.

Two discrete structural configurations are identified:

– The main, extradosed 3-spanned bridge of total length 400 m, above “Evros” river. The superstructure consists of 2 prestressed reinforced concrete, parallel box girders, transversely interconnected with crossbeams. A concrete slab connects the box girders.

– 2 access bridges of a length of 150 m on the Greek side and 291 m on the Turkish side. Both bridges are constructed of precast pre-tensioned T-beams within situ concrete slab.

The superstructure of the main bridge is supported on 2 pylons, symmetrically positioned on both sides of the borderline. The designed deep pile – foundation secures stability.
