Automation for the longest Balkan tunnel

Jun 02, 2016 Mark

Press Release ( - THESSALONIKI, Greece - Jun 02, 2016 - Project description
Subcontractors for SIEMENS for the automation of the SCADA/TMS system for the three tunnels under construction in the region “Tempi Valley”.

The 3 tunnels have a total length of 11 km (2km, 3km, and 6km). The third one is the longest in the Balkans and bypasses the winding and rock slide – plagued Tempi Valley on the main Athens-Thessaloniki highway.

The automation will supervise and control the following tunnel subsystems:

Lighting, Ventilation, Fire Detection, Fire Fighting, CCTV, Emergency Roadside telephones, Radio communication, Power Supply  distribution system, EDGs, Network Supervision, Traffic Data Counting System and Traffic Management System.


We designed our solution around SIEMENS SIMATIC S7-400H for a fault-tolerant automation system, which minimizes the probability of a failure to nearly 0%!
In each tunnel we used the CPU 417-5 H controller to collect all the control signals and perform the automation program. We used SIEMENS ET200S series in over 100 remote I/O, for the benefits of the highest quality and the
extremely rugged design.
The project has a total of over 10.000 physical control points, and over 7.500 network measurements and information.
We developed the automation according to the design and we are moving to the commissioning stage of the project.


This is a major infrastructure project for Greece with major benefits. The drivers will experience uninterrupted and constant traffic flow even in adverse weather conditions, cleanliness and respect for the surrounding area and maximum road safety and economy! At the same time, the region will benefit from the provision of many direct and indirect jobs and environmental protecton of the Tempi Valley due to reduced pollution levels!
