The A8 motorway (Croatian: Autocesta A8) is a 64.0-kilometre (39.8 mi) toll motorway in Croatia. It connects the A7 motorway near Rijeka with the road network in the Istrian peninsula via the Učka Tunnel. The road terminates at the Kanfanar interchange with the A9 motorway, which with the A8 motorway forms the Istrian Y road system. The motorway's national significance is reflected in its positive economic impact on the cities and towns it connects, as well as its importance to tourism in Croatia. The importance of the motorway for tourism is particularly high during the summer tourist season, when its traffic volume increases by about 65%.
