The Longest Suspension Bridge in the World Connects Asia to Europe


Listen Later

The recently opened 1915 Çanakkale Bridge in Turkey is an engineering marvel. The world’s largest suspension bridge, the project was thought to be technically impossible as late as the mid-1990s but has emerged as a key link between Europe and Asia.

The bridge required very high towers and large, submerged caissons built on-site, as well as advanced project management and planning. Some 4,000 workers built the bridge which—despite COVID-19—was completed ahead of schedule. A consortium of two Korean and two Turkish engineering firms handled the construction, and will operate the bridge for 16 years before turning control over to the Turkish government. The estimated cost of the project is $2.7 billion, and it is expected to carry as many as 45,000 vehicles per day.
