DESIGNING A WORLD RECORD SETTING BRIDGE FOR THE 21ST CENTURY

Serving as the centrepiece of the Malkara-Çanakkale Motorway Project in northwest Turkey, the 1915 Çanakkale Bridge crossing over the Dardanelles Strait will break the world record for the longest span of any bridge in the world at 2,023m when it opens to traffic in 2022.
The new bridge and motorway will feature three lanes in each direction and is expected to ease traffic congestion, reduce travel times, improve road safety, enhance national road network integration, boost economic activity, generate jobs during both construction and management, and create opportunities for domestic and international tourism.
In addition to the challenging ground and wind conditions, complex ship impact assessments and compressed project timeline, the bridge is being built in an area of high seismic activity, placing additional demands on the design. The two tower foundation caissons, each with a base area of 6164 m², are being constructed in dry dock and then floated out to the wet dock for the offshore construction stage before they are finally placed at 37 to 45m water depth.
