The Panagopoulas Tunnel (official name: “Andreas Papandreou” Tunnel) is a twin tunnel 4 km long and is one of the most important technical projects of Olympia Odos. The tunnel was opened to traffic on April 11, 2017 in the presence of Prime Minister Alexis Tsipras. The works started in 2008 together with the rest of Olympia Odos, but stopped in 2011. The works continued from the beginning of 2014. The 4 km tunnel is the largest road bridge of Olympia Odos and the third largest in Greece.

It is named after the homonymous seaside location of the Local Community of Ziria in Egialia.

Specifications

It is the largest tunnel of Olympia Odos and is the third largest in Greece, smaller than the T2 Tempi tunnel and the Driskos tunnel.

The two branches of the tunnel, 4,000 meters long on the right [2] and 3,160 meters on the left, have 3 escape tunnels, 5 connecting tunnels for vehicles, as well as 5 parking spaces per tunnel, 50 meters long each space. Also, every 150 meters there are SOS telephones on the right side of the tunnels, every 50 meters there are fire extinguishers for fire or explosion inside the tunnels.

The simultaneous construction of the OSE railway tunnel, under the road tunnels is quite remarkable since, the two manufacturers had to make sure the isolation of the intersections was such in order to isolate the effect of one project on the other.
