Istanbul City Tour - Turkey
Bosphorus River Cruise
An inexpensive way to explore the Bosporus is offered by the public ferries that traverse the Bosporus from Eminönü on the historic peninsula of Istanbul to the Black Sea, zigzagging between the Rumelian and Anatolian sides of the city.
The Bosphorus, is a strait that forms the boundary between the European and Asian part of Turkey. It is approximately 30 km long, with a maximum width of 3,700 metres at the northern entrance, and a minimum width of 700 metres. The depth varies from 36 to 124 metres in midstream.
Two bridges cross the Bosporus. The first, the Bosphorus Bridge, is 1074 metres long and was completed in 1973. The second, Fatih Sultan Mehmet Bridge, is 1090 metres long, and was completed in 1988 about five kilometres north of the first bridge.
Plans for a third road bridge, which will allow transit traffic to by-pass the city traffic, have been approved by the Ministry of Transportation. The bridge will be part of the "Northern Marmara Motorway", which will be further integrated with the existing Black Sea Coastal Highway. The location will be somewhere north of the existing two bridges, but the exact path is kept secret to avoid an early boom in land prices.
Another crossing, Marmaray, is a 13.7 kilometre-long undersea railwaytunnel currently under construction and is expected to be completed in 2012. Approximately 1,400 metres of the tunnel will run under the strait, at a depth of about 55 metres.
