The single carriageway tunnel that provides a fast and safer link between Fethiye, Gocek, Dalaman Airport and beyond could soon have a twin.

Works to construct a new tunnel by the existing Dalaman Tunnel started last week.

The civil engineering is estimated to take up to 800 days (2 years +) and construction will take place uninterrupted during that period.

The existing tunnel was completed in 2006 on a build and operate contract.

Work originally started on the 960 metre tunnel in 1989 but it took private finance funding and management to finally see its completion.

If all goes to plan we could see the new tunnel completed by 24 November 2015 and, according to reports, it is likely to be free to use too.
