DESIGN

Divel developed the Main Designs for both motorways and expressways to the length of 109.6 km, which included designs for 74 bridges with a total length of 12,100 m, as well as the designs for nine tunnels with a total tube length of over 24 km, among which are the Crni Vrh Tunnel 2,200.00 m, the Suhodol Tunnel (November 25th ) 2,930 m, the Vijenac Tunnel (March 1st) 2,970 m, to name but a few. Furthermore, the designs were also developed for 6,800 m of retaining and cladding structures, as well as for 70 other structures (underpasses, overpasses, interchanges, hydrotechnical facilities, etc.), including the traffic design of the A1 Motorway (Kakanj - Jošanica).

The company is also heavily involved in projects for the construction, modernisation, reconstruction and rehabilitation of motorways and regional roads, as well as a number of associated bridges (66 structures), tunnels (15 tunnels and galleries) and rehabilitation of landslides and rockfalls. The company has also completed traffic designs for over 850km of F BH Motorways.

Allow us to point out the main design of the 37 km long Neum-Stoc Main Road, linking Neum to the hinterland of Bosnia and Herzegovina, as well as the reconstruction and rehabilitation projects of roads over 830 km long. As for the network of motorways and regional roads, 66 bridges, 16 tunnels and galleries have been designed. Among the large-scale and complex structures we worked on, we are especially proud of the design of the bridge over the Jablanica Lake (550 m long) and the bridge on the Čemerno Pass (400 m long).

The projects related to stabilization, reconstruction and improvement of the level of service of the existing tunnels are undoubtedly very complex and demanding projects by any standard. When it comes to tunnel construction, Divel has worked on and completed many tunnel designs, among which the most significant are undoubtedly the "Vranduk 2" Tunnel on the M-17 Road (section Doboj – Lašva), the Karaula Tunnel on the M18 Road (section Kladanj-Olovo), the "Crnaja" Tunnel on the M-17 Road, (section Sarajevo– Jablanica), Ormanica Tunnel on the M18 Road (section Orašje-Tuzla), the Čaklovići Tunnel on the M4 Road (section Tuzla-Kalesija), the Karaula Tunnel on the M17 Road (section Ozimica-Topčić Polje), the Skela Tunnel (section Jajce-Donji Vakuf).
