Kherrata Tunnel is a road tunnel located in the municipality of Kherrata, pierced under the Babors, connecting the province of Béjaïa to that of Sétif. With a length of 7 km, it is the longest road tunnel in Algeria. The Kherrata tunnel consists of a single gallery for two-way traffic.

History

[edit]

The Kherrata tunnel was built by an Italian company. The structure was inaugurated in 1988 by the Algerian Minister of Transport.[1] In 2014, modernization works were carried out on the tunnel by a Spanish firm. The program included the replacement of lighting systems, ventilation and smoke extraction, and video surveillance.[2]

On June 17, 2017, a vehicle caught fire inside the tunnel. The fire did not cause any casualties. The tunnel was closed to traffic for several hours, resulting in a complete halt of road traffic on National Road 9. In confined spaces like tunnels, fires pose a high risk due to the difficulties of evacuating suffocating smoke, which is extremely dangerous for users.

Characteristics

[edit]

The Kherrata tunnel consists of three consecutive tunnels, with a total length of approximately 7 km. It is the longest road tunnel in Africa.

Traffic flows through a single tube with 2 × 1 lanes. The speed is limited to 80 km/h, and a safe distance between each vehicle is now required.

Usage

[edit]

The daily traffic through the tunnel exceeds 22,000 vehicles, reaching peaks of 30,000, especially during the summer season. Heavy trucks, which account for 45% of the traffic, are not allowed to use the tunnel in the ascending direction.
