Work on a major tunnel project in Algeria is due for completion shortly. The tunnel will commence carrying traffic during July 2016, although an official inauguration date has not so far been announced.

The T4 tunnel will connect Constantine with Skikda and Annaba, which lie to the north and on Algeria’s coast. The 2.5km tunnel forms a section of the East-West highway.

To cope with the tricky geological conditions in the area, both umbrella arch and composite roof bolting methods have been used to support the tunnel profile during the excavation work.
