Otoyol_30
Otoyol 30 (English: Motorway 30), also known as the Izmir Beltway (Turkish: İzmir Çevreyolu) and abbreviated as the O-30, is a 60.2 km (37.4 mi) long motorway that runs around the Gulf of Izmir from Balçova to Menemen.[1] The motorway acts as a bypass for through-traffic around the city and connects to four other motorways; O-5, O-31, O-32 and O-33. For most of its route, the O-30 runs along the perimeter of Izmir, but enters urbanized areas in Balçova, Bornova, Karşıyaka and Çiğli. The entire motorway has six lanes (three in each direction) and is a part of the E87 and E881.
The first section of the O-30 opened to traffic in 1993 with the most recent section opened in 2008.
