One of Bosnian officials in charge of plans for the highway, Namik Kupusovic, said that the said costs referred only to the construction and did not cover the costs of the purchase of land. The precise determination of the necessary funds is likely to be made by February 2006 when micro-locations of the route should be determined, too.
About 1.5 billion euros should be earmarked for the construction of bridges, viaducts and tunnels with the longest tunnel of about 6.5 six kilometres passing through Mount Prenj in Herzegovina. According to preliminary assessments, the Bosnian section of this pan-European corridor will be 340 kilometres long, including 75 kilometres of tunnels and 33 kilometres of bridges.
After passing through eastern Croatia, the highway will enter Bosnia in the northern town of Svilaj on the right bank of the Sava river. From Svilaj, the route continues via Modrica, Doboj, Zenica, to the capital of Sarajevo and further south to Mostar and the ancient town of Pocitelj by the Neretva River, and by the village of Medjugorje, a famous Catholic shrine, towards the southern border with Croatia. The exit point on the border with Croatia will be determined in cooperation with Croatia's authorities during September.
Kupusovic said that they would use the experience of Croatia in constructing two-lane parts of the highways where it is cost-effective.
Upon the construction of the Bosnian section, the travelling from Svilaj to the southern exit point will take some three hours.
