D528 connects the A4 motorway Varaždin interchange to the D2 and D3 state roads, just to the south of the City of Varaždin. The eastern terminus of the road is an intersection with the D2 and D3 state roads, which are concurrent at that location. The road is 2.4 km (1.5 mi) long. The road, as well as all other state roads in Croatia, is managed and maintained by Hrvatske ceste, state owned company.
