D301 is a state road connecting A9 with Novigrad and D21 state road. The road is 17.0 km long.[1] [2]
The road, as well as all other state roads in Croatia, is managed and maintained by Hrvatske ceste, a state owned company.[3]
Traffic is regularly counted and reported by Hrvatske ceste, operator of the road.[4] Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road connects A9 motorway carrying substantial tourist traffic to Novigrad, a major summer resort.
