Bosphorus Strait in the context of "Boundary between Asia and Europe"

Fatih (Turkish pronunciation: [ˈfaːtih]) or the Historical peninsula (in Turkish: Tarihi Yarımada), is a municipality and district of Istanbul Province, Turkey. Its area is 15 km, and its population is 368,227 (2022). It is home to almost all of the provincial authorities (including the mayor's office, police headquarters, metropolitan municipality and tax office) but not the courthouse. It encompasses the historical peninsula, coinciding with old Constantinople. In 2009, the district of Eminönü, which had been a separate municipality located at the tip of the peninsula, was once again remerged into Fatih because of its small population. Fatih is bordered by the Golden Horn to the north and the Sea of Marmara to the south, while the Western border is demarked by the Theodosian wall and the east by the Bosphorus Strait.

The Otoyol 7 (O-7; English: Motorway 7), or Northern Marmara Motorway (Turkish: Kuzey Marmara Otoyolu), is a toll motorway in Turkey that bypasses Istanbul to the north. The motorway is 248 km in length between the Kınalı junction and the Akyazı junction, and is 8 lanes wide (4+4 lanes).Within the scope of the Build-Operate-Transfer Model Construction, Operation and Transfer of Kınalı-Odayeri (Including Connection Roads) Section (North Marmara Europan Motorway) and Kurtköy-Akyazı (Including Connection Roads) Section (North Marmara Anatolian Motorway) of the Northern Marmara Motorway (Including the 3rd Bosphorus Bridge) Project, it is composed of two separate authorized companies, namely "AVRUPA OTOYOLU YATIRIM VE İŞLETME AŞ". on the European side and "KMO ANADOLU OTOYOLU İŞLETME AŞ". on the Asian side.

The completed section of highway crosses the Bosphorus Strait via the Yavuz Sultan Selim Bridge, which was opened in August 2016. The route is intended to serve as the outermost beltway of Istanbul as well as being the third road crossing of the Bosphorus. The route stretches 250 km (160 mi) from Silivri, on the European side, to Akyazı on the Asian side. Connections to the O-4 as well as both the Bosphorus and Fatih Sultan Mehmet bridges will be built as the Northern Marmara Motorway and will bypass Istanbul to the north.

The Port of Constanța is located in Constanța, Romania, on the western coast of the Black Sea, 179 nautical miles (332 km) from the Bosphorus Strait and 85 nmi (157 km) from the Sulina Branch, through which the Danube river flows into the sea. It covers 3,926 ha (9,700 acres), of which 1,313 ha (3,240 acres) is land and the rest, 2,613 ha (6,460 acres) is water. The two breakwaters located northwards and southwards shelter the port, creating the safest conditions for port activities. The present length of the north breakwater is 8,344 m (5.185 mi) and the south breakwater is 5,560 m (3.45 mi). The Port of Constanța is the largest on the Black Sea and the 17th largest in Europe.

The favourable geographical position and the importance of the Port of Constanța is emphasized by the connection with two Pan-European transport corridors: IV (high speed railway&highway) and the Pan-European Corridor VII (Danube). The two satellite ports, Midia and Mangalia, located not far from Constanța Port, are part of the Romanian maritime port system under the coordination of the Maritime Ports Administration SA.
