Major milestone for SYSTRA on a tunnel project in Türkiye

The Sarıyer – Kilyos Highway Tunnel Project will ensure high standard direct transportation between two strategic locations in İstanbul, from the Third Bosphorus Bridge to southern parts of the city. For motorists journey times will be reduced, as well as air and noise pollution.

Designed entirely by SYSTRA Türkiye’s underground experts, the Sarıyer – Kilyos tunnel will soon be dug by a tunnel boring machine (TBM). This machine, with a cutting diameter of 13.75 metres, is currently being assembled deep underground in Istanbul, in a cavern of impressive dimensions:

When it is put into action, the TBM will begin by assembling the first rings of segments to form a pre-tunnel, then will pierce the spandrel where the steel reinforcement has been specially designed to be perforated.
