It is instead tolled as part of the A1 system, and it includes the Mali Prolog viaduct (278m), the Mali Prolog tunnel (1029/1092m), the Kobiljača tunnel (769m), the Brečići-Struge viaduct (598m), the Puljani tunnel (320m), and the Kula viaduct (448m).

Traffic volume 

Road traffic in Croatia is regularly counted and reported by Hrvatske ceste, the operator of the road. The traffic entering D425 specifically is counted by Croatian Motorways Ltd at the Karamatići entrance.

Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road serves as a connection to the A1 motorway and the D8 state road carrying substantial tourist traffic.
