 The A3 motorway (Croatian: Autocesta A3) is a major east – west motorway in Croatia connecting the capital of the country, Zagreb, to the Slavonia region, where the motorway follows a route parallel to the Sava River and further on to Serbian and Slovenian motorway networks. As a part of the road network of Croatia, it represents a part of European route E70 Bordeaux – Turin – Ljubljana – Zagreb – Belgrade – Bucharest. The motorway has facilitated accelerated economic development in the regions it connects. The motorway also connects to a number of other motorways in Croatia (from the west to the east): the A2 at the Jankomir interchange, the A1 at Lučko interchange, the A11 at Jakuševec, the A4 at Ivanja Reka and the A5 at the Sredanci interchange.
