Turkish tunnel tender underway

The tender process is underway in Turkey for a major tunnel project. The package of works is for the planning, project and engineering design for a new three-storey underwater tunnel that is planned for Turkey’s commercial centre, Istanbul. Named the Big Istanbul Tunnel, the route is expected to run under the Bosporus. The tunnel is anticipated to feature two storeys carrying vehicle traffic, with a third carrying a rail link. This would cut journey times to just 14 minutes. The engineering work is expected

In addition the main cable stay bridge for the Busan-Geoje project has a 475m span rather than the 800m of the Incheon central span. However the 8.2km Busan-Geoje project faces perhaps greater technical challenges and also includes a second b
