2- Eastern Andalusia Tunnels

Description of the visit

In the eastern part of the south of the Iberian Peninsula, parallel to the Mediterranean coast, the A-7 motorway runs between the provinces of Almería, Granada and Málaga, overcoming its difficult orography through 23 tunnels (46 tubes) with a total length of 33 .5 km. Among them, the 1,256 m Churriana tunnel near Malaga airport and the 2,170 m Cantalobos tunnel between Nerja and Almuñecar stand out. The Aguadulce tunnel, 1,000 m long, is located in the province of Almería in a specifically complex area from a geotechnical point of view.

On the other hand, to the north of Malaga on the AP-46, the Alto de las Pedrizas highway (Málaga), there are three other tunnels (Cerro Negrete, Lechón and La Zambra), among which the 1,375 m Lechón tunnel stands out.

The management of all these tunnels is carried out from two Control Centers located in Torremolinos, Casabermeja and La Herradura.
