Petrovac tunnel on D425

The road, as well as all other state roads in Croatia, is managed and maintained by Hrvatske ceste, a state-owned company.[4]

History

The road was initially built as a single connector route between the A1 and the Port of Ploče, at the time designated as part of A10.[5] The dual carriageway part of the route was built in two phases, the first between finished in December 2008,[2] and the second in December 2013.[1] The dual carriageway extends from Karamatići to the Radonjić Viaduct.[5]

Under the current official road classification, as of 2016, the D425 ends at the toll station, while the continuation of the road to the north, a 6.6 km (4.1 mi) expressway connector from the Karamatići toll plaza to the A1 Ploče interchange,[6] is not classified as part of the D425.[3] 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).[6][7]

Traffic volume

Traffic is regularly counted and reported by Hrvatske ceste, the operator of the road.[8] 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.
