The object of the operation concerns the construction of the road bypass south of the village of Halkiou along the road road Chios — Chalkios — Vessa — Agia Irini and connection to the already constructed road bypass of the village Zifias. The aim is to increase traffic capacity and improve road safety, as the existing road has insufficient geometric and functional characteristics, for the safer and faster connection of the settlements of South and Southwest Chios with the entrance and exit gates of the island.
