Turkey’s Bosphorus sub-sea tunnel links Europe and Asia

A railway tunnel underneath the Bosphorus Strait has been opened in Turkey, creating a new link between the Asian and European shores of Istanbul.

The Marmaray tunnel is the world’s first connecting two continents, and is designed to withstand earthquakes.

It was inaugurated on the 90th anniversary of the Republic of Turkey.

Turkish Prime Minister Recep Tayyip Erdogan has for years championed the undersea engineering project, first conceived by an Ottoman sultan in 1860.

Work began in 2004, but archaeological excavations delayed construction.

The underwater section runs for 0.8 miles (1.4 km), but in total the tunnel is 8.5 miles (13.6 km) long.

In theory it brings closer the day when it will be possible to travel from London to Beijing via Istanbul by train.

The Marmaray project will upgrade existing suburban train lines to create a direct link joining the southern part of the city across the Bosphorus Strait.

The rail service will be capable of carrying 75,000 people per hour in either direction.
