D3 road (Croatia)
road in Croatia
D3 is a state road in western parts of Croatia connecting Rijeka on the Adriatic coast to Zagreb, Karlovac and Varaždin, as well as to the Goričan border crossing to Hungary. Furthermore, the D3 is used as a parallel road to a number of motorways in Croatia – namely the A4 motorway north of Zagreb, the A1 motorway between Zagreb and Bosiljevo 2 interchange south of Karlovac and finally the A6 motorway between Bosiljevo 2 interchange and Rijeka – and it connects to nearly all motorway interchanges on that route either directly or via connecting roads. The road is 218.4 km (135.7 mi) long.
The D3 state road is concurrent along parts of its route with other state roads, most notably the D1 between Zagreb and Karlovac, as well as some sections of the A4 (south of Popovec interchange) and the A3 (between Ivanja Reka and Lučko interchanges) motorways. The A3 and A4 motorway sections that are concurrent with the D3 state road are also a part of Zagreb bypass and are not tolled.
The road, as well as all other state roads in Croatia, is managed and maintained by Hrvatske ceste, a state-owned company.
Traffic volume

This brief starts where responsible research should: with the source description of “D3 road (Croatia)” as road in Croatia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as road in Croatia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 1, 2026. The linked authority identifier is Q3512354. Authority coordinates are 45.694, 15.748. None of the 1 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
