Bosphorus Bridge

Bosphorus Bridge

1973 - Bosphorus Bridge

  • 1074m main span suspension bridge
  • 60m vehciles cross the bridge per year
  • Bosporus Strait is one of the world's busiest water ways

A bridge not only to link both parts of Istanbul but a bridge to link people and nations as well.

Dr William Brown

Bridging the mighty Bosphorus Strait in Istanbul would connect Europe and Asia for the first time since 512bc.

It has had an astonishing effect on the city and people of Istanbul. It quite literally bridged the gap between the two sides of the strait, easing transport problems and fostering closer working relationships in the reunited city.

The population of the city has increased from under two million in the early 1970s to over 15 million today. The Bosphorus Bridge has been described as the catalyst for the socio-economic development of Istanbul and of Turkey.

Bill Brown

The Severn Bridge, with its innovative box girder deck, was a turning point in Bill Brown's career. Bill was being regarded as one of the leading engineers of his age.

In the late 1960s and early 1970s, he oversaw the design and structural engineering of the Bosphorus Bridge, working with the expert team at Freeman Fox & Partners.

It was constructed in record time, taking 400 workers and 35 engineers just over three years to complete. The bridge opening in 1973 attracted a crowd of over one million.

It became the bridge with the longest main span in Europe (1,074 metres) and fourth longest in the world. In the 1980s, Bill Brown was appointed as engineer for construction of the second Bosphorus Bridge.

Messina Strait Bridge

Bill Brown's career reached a fitting conclusion when he became head designer for the proposed Messina Strait Bridge from Italy to Sicily. He devised an ultra-long 3,300m single-span suspension bridge with an innovative multi-box deck.
