The Kvanj - Buna Tunnel sub-section financed from funds provided by the European Investment Bank (EIB) in the amount of EUR 100 million, and it has also been applied for EU grants through the Connecting Agenda through the Western Balkans Investment Framework (WBIF).

In January this year, the sub-section was cleared of mines and explosives, which created the conditions for the safe continuation of the construction of the highway on Corridor VC in the south.

The construction of the section Mostar South - Buna, which is divided into two subsections Mostar South - Tunnel Kvanj and Tunnel Kvanj - Buna, will connect Mostar with the European motorway network and form a functional uninterrupted motorway from the Bijača border to the entrance to Mostar. invaluable for BiH citizens, companies and entrepreneurs.
