The A2 motorway (Slovene: avtocesta A2, Ilirika) is a motorway in Slovenia, around 175 km long, connecting the Karavanke Tunnel (at the Austrian border) via the capital city Ljubljana to Obrežje (at the Croatian border, near Zagreb). It connects several major Slovene cities, including Kranj, Ljubljana, and Novo Mesto, and is part of Pan-European Corridor X.
The route of the motorway largely follows the path of the Brotherhood and Unity Highway, which was a two-lane non-divided road constructed as the main traffic artery within Yugoslavia. With the construction of the divided motorway, most of the previous road was demolished. A notable exception can be seen on the southern A2 segment between Grosuplje and Višnja Gora, where the previous road was grandfathered into the motorway system; it lacks a hard shoulder and has sharp turns and an exit ramp with a 10% grade. The northern segment between Višnja Gora and Grosuplje follows a completely different path, with three traffic lanes and a relatively lower grade.
