A2 motorway (Serbia)
The A2 motorway, called the Miloš the Great Motorway is a motorway in Serbia under construction and when finished it will span for approximately. It begins in Belgrade and runs southward to Čačak and Požega, then going further south towards Montenegro ending at future Boljare border crossing. This motorway will thus provide faster link with Montenegro by attaching to its Bar-Boljare motorway, currently under construction.
It is frequently referred in Serbian media as part of proposed Corridor XI - an envisioned ferry/motorway corridor linking Bari, Bar, Belgrade and Bucharest.
