The A1 motorway (Croatian: Autocesta A1) is the longest motorway in Croatia, spanning 478.9 kilometers (297.6 mi). As it connects Zagreb, the nation's capital, to Split, the second largest city in the country and the largest city in Dalmatia, 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, provides access to several national parks or nature parks, world heritage sites, and numerous resorts, especially along the Adriatic Coast. 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.
