Despeñaperros Tunnel

The Despeñaperros tunnel is a double tunnel that crosses a mountain range in the Sierra Morena, in the province of Jaén. It forms part of the A-4 highway, making it the longest tunnel in Andalusia at 1925 metres long.

Designed to improve road connections between Andalusia and the north of the country, it was inaugurated in June 2012. Caldibe manufactured the tunnel formwork used in this project.
