D501 is a state road connecting D3 state road and the A6 motorway Oštrovica interchange to littoral area between Kraljevica, Crikvenica and Novi Vinodolski as well as the island of Krk, terminating at D8 intersection near Jadranovo. The road is 20.3 km long.
D501 is a connecting route providing a link between two major state roads (D3 and D8) and one motorway (A6). An additional motorway interchange, to A7 is planned, in Meja interchange, which is currently under construction.
Traffic is regularly counted and reported by Hrvatske ceste, operator of the road. Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road serves as a connection to A6 motorway and D8 state road carrying substantial tourist traffic.
