During the upgrade of the Rijeka Bypass to full profile 8.86 km long south carriageway from Orehovica to Diračje Interchange was built, starting at the beginning of 2008, and ending by the end of 2009. Since the Rijeka Bypass passes through the urban area, special attention was given to noise protection, resulting with the largest and the most complex noise protection project of its kind in the Republic of Croatia. As a result of complex requirements of noise protection in the vicinity of 5 high skyscrapers in the Rastočine area, an 352 meters long arch structure over the bypass south carriageway was constructed. Further the structure was designed in a way as to integrate a dual function: noise protection for the tenants, living in the four nearby skyscrapers, and electrical energy production.
