The Xanthi - Echinos road is located in northern Greece, near the Bulgarian border. The project concerned the transportation / road-engineering study of a total road length of 9 km, having one 3.75 m wide lane per direction and a hard shoulder of 1.25 m. The project comprised the complete road design study, the environmental impact assessment study, and the final design of 5 major bridges (total length: 215 m), 3 small bridges (total length: 50 m), and 3 cut-and-cover works (total length: 388 m). Within the framework of the project, field surveys, topo-map elaboration, geological and geotechnical studies, as well as hydraulic studies at the final design level were also carried out.
