The Istanbul Strait Road Tube Crossing project is based in Istanbul and includes tunnel construction, road widening, access ramps and an upgrade of the current operational management and control systems.

The aim of the project is to ‘provide a bi-directional, safe, robust, reliable, comfortable, durable and uninterrupted transportation of light vehicles under the Istanbul Strait for a design life of 100 years’. We took the first step of the project with fire testing of tunnel floor components.
