The project concerns the upgrading of the section “End of Gravia Bypass – level Voxitis Mining Node”, with a total length of 4.70 km, the Lamia – Itea – Antirrio road axis. This section begins at the end of the Gravia bypass, mostly improving the existing road in the Stenorema area, and further mapping thereafter to avoid successive closed corners of the existing road. The object of the project to be constructed includes the execution of all types of earthworks, technical works (carves, bridges, walls, cradles, paving, etc.), works of protection against falls, road paving, asphalt, marking (vertical and horizontal), locking, enclosure of road works, sewerage and drainage, with an electromechanical installation (dwelling of outdoors, etc.) will be provided. In addition, 2 level knots (Vargiannis and Vauxite Mines) will be constructed, with a retaining walls of approximately 590 m, 1 bridge with a total length of 121.50 m and a width of 18.25 m, small technical walls and intercepting trenches. Also, the project foresees work on shifting – restoring networks of Public Benefit Organisations (OKOs) and connecting with them, archaeological research and work and the required expropriations.
