The M-50 orbital motorway is the outermost ring road of Madrid and its metropolitan area. It has a length of 85 km (53 mi) and, unlike the other ring roads, doesn't form a closed ring, lacking a connection in the northwest between A-6 and A-1. It runs at an average distance of 13.5 km (8.4 mi) from the Puerta del Sol. It is the longest beltway in the Madrid region, and may be compared with London's M25 motorway and Berlin's A10 beltway.
It is managed by the central government. Its construction was financed using a shadow toll system, paid with the tolls collected from the motorways R-2, R-3, R-4 and R-5.
