About the project:
The bridge over the Trebišnjica River in Trebinje is the biggest and the most important structure on the future east bypass that will connect roads for Herceg Novi and Dubrovnik with roads toward Bileća and Nikšić. The construction of east bypass shall relieve the center of Trebinje from traffic and significantly reduce travel time. The main bridge structure is a monolith reinforced prestressed concrete structure with 13 spans. The designed length of bridge amounts to l=484 m, and the width amounts to Bv=11.60 m.
Scope of works:
The construction of bridge structure will be performed by scaffolding tehnology. The span structure is designed as continuous, prestressed box structure with vertical walls and spans of 26.00 + 4 x 36.0 + 2 x 54.0 + 5 x 36.0 + 26.00 = 484.00 m. The bridge width is 11.60 m.
The design envisages three foundation types: shallow foundation in axes 1, 2, 3, 4, 5, 9, 10, 11, 12 and 13, drilled shaft foundations in axes 6 and 7 and pile foundation in axis 8.
The piers are 2.50 m in diameter and they are of different heights. The height of piers: in axis 2 – 8.5 m, in axis 3 – 12.5 m, in axis 4 – 19.5 m, in axis 5 – 26 m, in axes 6 and 7 – 28.0 m, in axes 8 and 9 – 23.0 m, in axis 10 – 21.0 m, in axis 11 – 14.0 m, in axis 12 – 10.0 m and in axis 13 – 9.0 m.
The bridge construction project includes the installation of traffic signalization and bridge equipment, as well as of public lighting.
