The A1 motorway (Slovene: avtocesta A1) is 236,1 km long, connecting Šentilj (at the Austrian border) and Koper/Capodistria (on the shores of the Adriatic Sea). It passes several important Slovenian cities, including Maribor, Celje and Ljubljana all the way to the Slovenian Littoral and Koper, with its important port.

Construction began in 1970 and the first section was finished in 1972, connecting Vrhnika and Postojna. Everyday operation of this initial stretch started on 29 December 1972.

The connection to Koper was finished on 23 November 2004. The second-to-last part, from Trojane to Blagovica, was opened on 12 August 2005. It was also the most expensive, having eight viaducts and two tunnels despite being only 11 km long. The final section, the eastern Maribor bypass, opened on 14 August 2009.
