Viaduct #2

The Vranduk – Ponirak section is one of the most challenging routes on Corridor Vc in Bosnia and Herzegovina. Due to the steep mountainous terrain and strict demands for a 100-year structural lifespan, the engineering team at INFRA d.o.o. Sarajevo successfully optimized the original main design, delivering innovative and cost-effective structural solutions tailored to the contractor's available equipment.

Viaduct #2: Advanced Cantilever Construction Viaduct 2 (169m) is designed as a prestressed concrete continuous box-girder structure for both left and right bridges, specifically optimized for rapid construction.

  • Construction Method: Engineered using a combination of the balanced cantilever method (free cantilever) and fixed scaffolding to maximize efficiency.
  • Substructure: Supported by innovative split-pier structures (6.20 x0.80 m) reaching heights up to 25.5m. To control slenderness on the tallest piers, a solid cross-section was implemented in the lower segments.
  • Foundations: The main piers are supported by six bored piles, are founded directly on solid limestone bedrock.
