Autostrada A50 or Tangenziale Ovest di Milano ("Milan west ring road")[1] is an autostrada (Italian for "motorway") 31.8 kilometres (19.8 mi) long in Italy located in the region of Lombardy that connects the suburban area of Milan from south-east to north-west, managed by Milano Serravalle – Milano Tangenziali.
Together with the Autostrada A51 (Milan east ring road), the Autostrada A58 (Milan external east ring road) and the Autostrada A52 (Milan north ring road), it is the largest system of ring roads around a city in Italy, for a total length greater than 100 kilometres (62 mi).
[2] By adding the urban sections of Autostrada A1 and Autostrada A4, which runs parallel to the northern ring road by connecting Autostrada A51 and Autostrada A50, to the three ring roads, a system of urban motorways is obtained that totally surrounds the city.
The traffic flow that affects this stretch of motorway is around 250,000 daily transits.
