Planning and construction of major infrastructure works in Croatia

The paper presents recent accomplishments in tunnel construction in Croatia, which was part of a much bigger undertaking - development of national motorway network. Over the last decades Croatia made large investments in order to construct the planned 1500-km of motorways. The total length of motorways and semi-motorways currently operated in Croatia amounts to 1020 km, half of which were constructed over the past 5 years. Further works comprise extension of motorway network, as well as rehabilitation of older sections. Development of highway network required construction of a large number of motorway structures. Overall 55 tunnels will in the end provide for little over 86 km of Croatian motorways, including two longest tunnel structures in Croatia: Sveti Rok tunnel (5670 m) and Mala Kapela tunnel (5780 m) completed in 2003 and 2005, respectively.
