The Motorway on the Corridor Vc is a part of the Trans-European ground corridor network connecting the central part of the Adriatic Sea coast with Budapest in Hungary. Corridor Vc stretches from Kaliningrad (Russia) in the North to Ploče (Croatia) in the South. The Corridor, 330 km long, runs North-South through the heart of Bosnia & Herzogovina, passing through ecologically important areas such as the Bosna and Neretva River valleys. The potential environmental impacts of the proposed motorway have been assessed in four separate Environmental Impact Assessment reports over the full length of the route, which has been divided into four sections. Of particular concern to the NGO Fondeko are the possible impacts of the motorway in the 3rd section which runs from Sarajevo South (Tarcin) – to Mostar North. This section runs through a 6.4 km long tunnel under the Prenj Mountain, bordering on the future Prenj-Cvrsnica-Cabulja National Park, designated for preservation due to its extraordinary biological and geomorphologic diversity which includes an endemic sub-mountain forest of Bosnian pine (Pinus heldeichii). Despite numerous attempts to point out the unsuitability of this motorway passing near the future national park, the attempts of NGO FONDEKO to propose an alternative route have been ignored by authorities. This NGO continues to use all varieties of media (radio, TV, journals) to point out the potential problem, but so far without success.
