|State roads in Croatia|
The road, as well as all other state roads in Croatia, is managed and maintained by Hrvatske Ceste, state owned company.
The D520 state road traffic volume is not reported by Hrvatske Ceste, however they regularly count and report traffic volume on the A3 motorway Babina Greda interchange, which connects to the D520 road only, thus permitting the D520 road traffic volume to be accurately calculated. The report includes no information on ASDT volumes.
