COWI moves up the ENR ladder with new record-breaking bridge

This year's prestigious ENR Global Sourcebook rankings are out and COWI takes an impressive third place within bridges. The world’s largest suspension bridge, the 1915 Canakkale Bridge in Turkey, recently entered the order book.


COWI has been awarded the contract for the detailed design of a record-breaking suspension bridge across the Dardenelles Strait near Canakkale in western Turkey.

COWI is carrying out the detailed design for the EPC contractor Joint Venture DLSY consisting of Daelim (Korea), Limak (Turkey), SK E&C (Korea) and Yapi Merkezi (Turkey).

With a span of 2023m, the 1915 Canakkale Bridge will have the longest span of any suspension bridge in the world, surpassing the Akashi-Kaikyo Bridge in Japan, the current record holder at 1,991m.

Moving up the ladder

The award of the contract cements COWI's position as the global leader in the design of long span suspension bridges and paves the way to an impressive top 3 position within bridges in the ENR Global Sourcebook, an annual publication that compiles and publishes rankings of the largest construction and design firms, measured by international gross revenues.

“We are proud to have moved up from last year’s fourth place indicating that we are moving in the right direction,” says Senior Vice President for Bridges International Henrik Andersen.

"Moreover, we are thrilled to have won the contract for the detailed design of the iconic, record-breaking 1915 Canakkale Bridge. It reflects the technical excellence of our engineers and our proven track record of delivering innovative, buildable designs for major bridges."

Other ENR strongholds

The 1915 Canakkale Bridge is scheduled to open for traffic in 2023 on the 100 year anniversary of the declaration of the Republic of Turkey. It will form part of a new highway network linking Europe and Asia.

"We have mobilised a strong team that can deliver this fantastic bridge project on a very tight schedule," says Henrik Andersen.

COWI keeps a strong position in several other ENR categories. Not least, COWI keeps an impressive no. 1 position within Solid Waste with major ongoing projects in e.g. Indonesia, Egypt and Vietnam.
