Croatia’s national road construction and maintenance agency issued a tender for a feasibility study for a road transport corridor between the towns of Žuta Lokva and Križišće on Croatia’s northern Adriatic coast. A team of five key experts designed five conceptual solutions, then used multi-criteria analysis and cost-benefit analysis to select the best possible design. The chosen solution was a 56.5km two-lane road that will significantly improve road safety, reduce travel time, remove road traffic from inhabited areas, and provide better local, national, and international accessibility, while simultaneously improving environmental impact over existing roads and reducing emissions.
