The Aithra Tunnel (Greek: Σήραγγα Αίθρα) is a tunnel on the Athens-Corinth section of the A8 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 A8 and it is currently the second longest tunnel of it. It was opened to traffic in July 2004, along with the rest of the motorway segment, in time for the Athens Olympics.
