Bundesautobahn 999

Bundesautobahn 999 (translates from German as Federal Motorway 999, short form Autobahn 999, abbreviated as BAB 999 or A 999) was the designated number for the Mittlerer Ring in Munich, Germany, a projected second ring road around the inner city districts to accompany the Münchner Ring (Bundesautobahn 99). The project to construct the Mittlerer Ring as an autobahn was not carried out, instead the Bundesstraße 2R now covers most of the planned A 999 trajectory.
