The design was carried out within the context of the project: Design - Construction - Self-financing and Exploitation of Elefsina - Stavros - Spata Airport and Imittos Western Peripheral Motorway.

The project was conducted in three periods. During the first period (1983-1989) METHODOS ENGINEERING SA prepared the Final Design of the 5.5km of Aghia Paraskevi – Katechaki section with two interchange traffic junctions as well as the preliminary design of sections of Kontopefko - Aghia Paraskevi (1.5km) and Balana - Aghia Paraskevi (4km). That first design comprised a 2×2 cross-section with poor characteristics set by the Ministry for the Environment, Planning and Public Works as a result of the Katechaki – Karea section characteristics. Based on that design a small section of the main road (earthworks and basic infrastructure in Demokritos – Papagos section) was constructed.
