The CrossBorder Road project aimes to connect non-continuous roads in the Mittelburgenland Area and Szombathely – Köszeg – Zsira. It affects two street sections: First, the completion of the by-pass road „Therme Lutzmannsburg“ in Austria, started during the „Landmark-Rubber“ project (ETZ AT-HU 2007-2013) in Hungary. Second, the conjunction of the southern part of the road S31-B61a with the hungarian higher-ranking road network near Köszeg (State road Nr. 87).The main problem are missing or not fully developed cross-border roads, especially between Köszeg and Oberpullendorf and also the missing connection to the TEN-T road network.Project aim is the rearrangement and finishing of cross-border road network to ensure shorter and safer reachability of the TEN-T road network from Austria as well as from Hungary. The principal object is the rebuilding and extension of two road sections, which contains improvements for both countries as a result of faster and safer routes. It also improves conditions for international road haulage because of better connections to the higher-ranking road network. The project also implements the reduction of traffic which increases the environmental conditions for the sedentary population near the existing roads.The cross-border approach results from the need of a cross-country infrastructure because both countries already achieved massive preparatory work on each side of the border. In this case it is of particular importance to reconcile the planning process.
