The project entitled “Improvement of side roads of Corinth Tripoli from Target crossing to Makri Pass” includes the works to improve the network of the side roads of the Corinth Tripoli Kalamata motorway to a total length of 15 km. The project is located within the boundaries of the Tripoli Municipal Unit of the Municipality of Tripoli between the Passage that serves the settlement of Makri south of Tripoli and as its aim is the creation of a single functional network of adjacent roads of the Motorway. This project is part of the Priority Axis 4 “Development of modernisation of infrastructure for economic and social development” and in particular the thematic objective 7 “Promoting sustainable transport and removing obstacles with basic network infrastructures” of the Peloponnese. The existing network is non-continuous, with incomplete drainage conditions, resulting in urban road use, which is a deterrent to the development of new activities. The implementation of this project achieves the promotion of sustainable transport, the improvement of connections with the main road network and the trans-European axis, the improvement of accessibility in tourist areas and in areas of archaeological cultural interest, and the strengthening of commercial and craft uses developed on the roads of this road.
