Bosporus overhead line crossings
Bosporus overhead line crossings refers to the three transmission line crossings of the Bosporus, the strait in Istanbul, Turkey. 154 kV Vaniköy-Etiler 
The Bosporus overhead line crossing 1 was the first overhead transmission line crossing the Bosporus. It was inaugurated in 1957 and it is designed and operated for two 154 kV circuits. Although apparently designed for overhead ground wires, none are currently present. The span width is , clearance over Bosporus is . The pylons carrying this span are 113 metres tall. Coordinates

Crossing II 
Bosporus overhead line crossing 2 is the second transmission line across Bosporus. It is designed for two 420 kV circuits and it went in service in 1983. It has a span width of  and is mounted on 124 metres tall pylons. Coordinates

Crossing III 
Bosporus overhead line crossing 3 is the third overhead line crossing of the Bosporus. It is adjacent to the second crossing, and is designed for four 420 kV circuits, but can be used after some re-engineering work also for 800 kV lines. Since 1999, two of the four circuits are in use. The pylons on which the  crossing span is mounted are  high. Coordinates
