The A2 motorway () is a motorway in Slovenia, around 180 km long, connecting the Karawanks Tunnel (at the Austrian border) via the capital city Ljubljana to Obreà ¾je (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 Vià ¡nja 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 Vià ¡nja Gora and Grosuplje follows a completely different path, with three traffic lanes and a relatively lower grade.
From the northwest to the southeast, the A2 motorway features the following tunnels and covered cuts:
