This is the most interesting sections of the new state road across the Peljesac peninsula in Croatia.
Whole route is long about 35 km, cause to difficult terrain conditions there are several bridges and tunnels.
All design (except the Peljesac Bridge) was made by Croatian companies (IGH, IPZ, Palmoticeva 45).
For the Peljesac Bridge. design was made by Slovenian company Pipenbaher Consulting Engineers.
I only make a presentation for this projects (whole 35 km) , most using Autodesk Infraworks and Civil 3D. Some of the interesting sections I export and finish in the Twinmotion, for the better end result.
