Otoyol 7 in the context of "Motorway"

The 1915 Çanakkale Bridge (Turkish: 1915 Çanakkale Köprüsü) is a road suspension bridge in the province of Çanakkale in northwestern Turkey. Situated just south of the coastal towns of Lapseki and Gelibolu, the bridge spans the Dardanelles, about ten kilometres (six miles) south of the Sea of Marmara. The bridge is the longest suspension bridge in the world—with a main span of 2,023 m (2.023 km; 1.257 mi), the bridge surpasses the Akashi Kaikyo Bridge (1998) in Japan by 32 m (105 ft).

The bridge was officially opened by President Recep Tayyip Erdoğan on 18 March 2022 after roughly five years of construction. It is the centrepiece of the planned 321-kilometre-long (199 mi) US$2.8 billion O-6 motorway, which will connect the O-3 and O-7 motorways in East Thrace to the O-5 motorway in Anatolia. The year "1915" in the official Turkish name honours an important Ottoman victory in the Gallipoli campaign comprising an unsuccessful Entente naval attack followed by invasions of the Gallipoli peninsula by the forces of Australia, New Zealand, France, and Great Britain, on 25 April 1915 and a second in August; the Entente land forces failed to make significant progress and were evacuated at the end of that year.

Otoyol 3 (English: Motorway 3), also known as the European Motorway (Turkish: Avrupa Otoyolu) and abbreviated as the O-3 is a 245.1 km (152.3 mi) 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 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 (2nd Beltway) and Fatih Sultan Mehmet Bridge in the east direction, to 1st Beltway (O-1) with the O3-O1 connection road in the south direction. The motorway has six lanes, three in each direction, except for a 44.6 km (27.7 mi) section between Silivri and Esenyurt.
