Improvement of Agathoupolis I/C and Kleidi I/C. 10

11 The Project Construction of the New Part between Tempi and Skotina One of the major parts of the Project is the construction of three twin tunnels. These are Tunnels T1, T2 and T3 of 2km, 6km and 2,7km length respectively. Tunnels T1 and T2 will be located in the area of Tempi. Tunnel T3 will go through the area of Panteleimonas. Tunnels T1 and T2 will pass through mount Kissavos, while T3 through mount Olympos and the max. depth of their construction is close to 300 meters below surface. Each Tunnel will have two (2) driving lanes and an emergency lane per tube, thus having a width of approx. 10,5 m. Every approx. 300 meters there will be a cross passage to the other tube for pedestrian use in case of an emergency, while every 900 meters the cross passage can be used by the vehicles of the emergency services. 11
