croatia is is located in the middle of South-East Europe and on the July 1st, 2013, Croatia became the 28th member of the EU. South-East Europe is the EU region with the highest expectations and plans in developing infrastructure in next two decades in Europe. Therefore choosing Dubrovnik with its location in the middle of the South-East Europe region and in the heart of Europe we would like to make the sign to all other member nations where to go and where to intensify their activities in the soon future. So far none of SEE countries have had opportunity to organise a World Tunnel Congress and this happening will strongly and certainly help further development of underground infrastructure in the future. Dubrovnik is also a regional centre for infrastructure works with unique underground solutions (underground HPP Ombla, city road tunnel, light rail to airport, new road roundabout) that will all be in construction in 2015
