Otoyol 3
Otoyol 3, also known as the European Motorway and abbreviated as the O-3 is a long otoyol in East Thrace, Turkey. The O-3 runs from Edirne to Istanbul and is the only motorway in Turkey located entirely in Europe. The motorway begins west of Edirne at "Edirne Batı K1" junction with the State [road D.100 (Turkey)|D.100] where it then continues as a beltway passing just north of Edirne. From there, the motorway passes through mostly rural farmland until it enters the Istanbul metropolis near Silivri. The eastern end of O-3 ends at the Istanbul Bağcılar "Mahmutbey Batı K20" Junction.
O-3 "Avrupa otoyolu" "Mahmutbey Batı K19" junction connects to O-7, E80, Istanbul Airport and Yavuz [Sultan Selim Bridge] in the north direction, to Ataturk Airport with the 2nd Beltway in the south direction. The last junction of the European motorway "Mahmutbey Doğu K20" connects to O-2 motorway and Fatih Sultan Mehmet Bridge in the east direction, to 1st Beltway with the O3-O1 connection road in the south direction. The motorway has six lanes, three in each direction, except for a section between Silivri and Esenyurt.
