The Bosphorus Bridge is one of two bridges that spans the Bosphorus Strait, connecting the European and Asian sides of Istanbul. It stretches from Ortakoy on the European side to Beylerbeyi on the Asian side and is sometimes referred to as the First Bosphorus Bridge.
At 1560 meters long, the Bosphorus Bridge was the fourth longest suspension bridge in the world when it opened in 1973 and was the first bridge to connect Europe and Asia since a bridge spanning the Dardanelles in 480 B.C. Today, it is the 21st longest suspension bridge in the world. In 2007, an LED lighting system was installed to illuminate the bridge at night and the computerized system is now used to create a colorful light show every evening.
While the bridge is typically closed to pedestrians, it opens each October for the Istanbul Eurasia Marathon – the only marathon that crosses from one continent to another.
