The Driskos Tunnel (Greek: Σήραγγα Δρίσκου) is a 4.5 kilometres long tunnel on the A2 motorway (Egnatia Odos). It passes underneath the Mitsikeli mountain. Works began in 2001 as part of the Ioannina-Arachthos segment of the motorway, one of its most challenging and costly segments. Its construction faced challenges, as it was built under a mountain containing sandstone. It is the longest road tunnel of the whole A2 and it was the longest in Greece, until the 6 kilometres long T2 Tunnel of the A1 motorway completed in 2017.
