Participants of the 12th International Conference on the Bearing Capacity of Roads, Railways and Airfields (12th BCRRA 2026) are cordially invited to join a professionally guided technical visit to the construction sites of the Second Track Divača–Koper project, one of the most demanding infrastructure projects in Slovenia and the wider region.

The visit will last approximately two hours and will include an overview of the project’s key technical features, including the construction of more than 20 km of tunnels, the challenging geotechnical conditions of the karst terrain, modern engineering solutions and approaches, and specific characteristics of the railway infrastructure. The programme will be complemented by visits to some of the project’s most impressive construction locations.


The tour will be led by project representatives directly involved in the works, who will also be available for practical discussion and questions.
This visit offers a unique opportunity to gain first-hand insight into state-of-the-art railway infrastructure solutions and will serve as a valuable addition to the conference programme.
Please note that the number of places is limited, and advance registration is required.
We warmly invite you to take a closer look at Slovenia’s largest infrastructure project currently under construction.
