Geraneia Tunnel
The Geraneia Tunnel is a tunnel on the Athens-Corinth section of the Olympia Odos motorway. Works began in 1999 as part of the construction of the Kakia Skala pass, one of the most dangerous road parts in Greece, with motorway standards. It was one of the first tunnels of the motorway. It was opened to traffic in July 2004, along with the rest of the motorway segment, in time for the Athens Olympics.
