Slavonska Avenue is a limited-access avenue in Zagreb, Croatia. It is the longest street in Zagreb, being 18 km (11 mi) long. It mostly has a 70 km/h (43 mph) speed limit, although the speed is limited to 100 km/h (62 mph) on a short section near the Ivanja Reka interchange with the Zagreb bypass. In 2007 the avenue was proclaimed to be the most accident-prone road in Zagreb. The avenue is an important east-west arterial road. Starting at the interchange with Savska Road, it intersects, featuring mainly two and three-level interchanges, several other main Zagreb thoroughfares : Croatian Fraternal Union Avenue, Marin Držić Avenue, Vjekoslav Heinzel Avenue, Gospić Road, Ljudevit Posavski Road. Slavonska Avenue does not have any tram lines, although most lines in Zagreb pass over or under the avenue.
