 Since the 2000s multilane motorways have taken over most of its traffic, and yet more motorways are still being built along the coast.The motorways parallel to the road are A7 (Rupa border crossing-Sveti Kuzam), A6 (Rijeka-Bosiljevo) and A1 (Bosiljevo-Zadar-Split-Ploče).Since Adriatic Highway closely follows the well-indented Croatian coastline, travel is considerably longer and less safe compared to the motorways because of numerous blind curves and at-grade intersections.
