Let us begin with the most modern and outermost one for which, in fact, the circle has yet to be completely joined - that is, the system of "Tangenziale" around Milan, which are national-level bypass motorways around Milan. The system consists of the A50 in the west and south, the A51 in the east, and the A52 in the north which still has a missing link in its middle, a work in progress (presently connected by the fine highways of SP 46 and SP 33; but not yet up to full Autostrada grade).
|Google Streetview shows ongoing roadworks still in 2015 to upgrade SP 46 (Strada Provinciale) and also SP 33 (the missing links in A52) so that Tangenziale A52 can be complete - then the entire Ring of National Bypass Motorways around Milan (Tangenziali) will have been joined up. You can also go to the original streetview on Google Maps.|
