Project Information:
Twelve preliminary alternatives were proposed in total and the alternative Z was chosen and designed in the final stage . It concerns a 2+2 lane cross section with an emergency lane, with a total length of 12,69 m. At the start of the alignment the road axis is adjusted to the existing motorway. Just before the Pinios river a 700m. overpass crosses the new railway line. The settlement of Tempi Valley is bypassed by a twin tunnel (1795m.-1841 m. in length) Following the alignment of the existing National Road for 900m. we enter in the mountainous volume of Ossa with a twin tunnel of 5921m.-5966m (each branch length). At the exit of the tunnels the axis' alignment meets the one of the existing part of the Athens –Thessaloniki Motorway.
The design speed for the geometrical attributes of the chosen alternative (Z) is Ve=100 km/h.
