ArcelorMittal Galati supplied 34,000 tons of steel for the construction of one of the biggest bridges in the world. Inaugurated last week, the Ozman Gazi bridge cuts travel time between Istanbul and Izmir from nine hours to three and a half hours.
ArcelorMittal supplied Cimtas with flat steel products needed for the bridge’s platform. The 34,000 tons were shipped in four batches, in an extended range of thickness and width.
“The project had special meaning for us, given its size,” said Bruno Ribo, CEO of ArcelorMittal’s European Division for Flat Products, South East. “The thick sheet metal rolling mills in Galati are capable of manufacturing and delivering products for numerous applications. For the Ozman Gazi bridge, we created customized technical and commercial solutions.”
The bridge that spans Izmit Bay, in Turkey’s northeast, is part of a 420-km expressway that shortens the distance between Istanbul and Izmir by around 140 kilometres. The NOMAYG consortium (consisting of Turkey’s Nurol, Ozaltin, Makyol, Yuksel, Gocay and Italy’s Astaldi) handled the entire project and will offer maintenance works for a period of 23 years. The consortium awarded the bridge construction project to Japan’s IHI Corporation, on the basis of a tender. Cimtas was selected as sole manufacturer of the steel segments for the suspension cables and support pillars. The bridge was designed by Denmark’s Cowi industrial design company.
With a total length of 2,682 metres and a maximum opening of 1,550 metres between the main pillars, the Osman Gazi bridge is the longest suspension bridge in Turkey, the second-longest in Europe and the fourth-longest in the world.
