The A1 motorway is the longest motorway in Croatia, spanning 476.3 kilometers (296.0 mi). As it connects the nation's capital Zagreb, in the north of the country, to the second largest city Split on the shore of the Adriatic Sea, the motorway represents a major north–south transportation corridor in Croatia and a significant part of the Adriatic–Ionian motorway. Apart from Zagreb and Split, the A1 motorway runs near a number of major Croatian cities, and provides access to several national parks or nature parks, world heritage sites, and numerous resorts, especially along the Adriatic coast. The national significance of the motorway is reflected through its positive economic impact on the cities and towns it connects as well as its importance to tourism in Croatia.
