Egnatia Odos Motorway

Structural Design of tunnels and bridges, Northern Greece

The Firms involvement in this Motorway
comprises mainly structural design of
tunnels and bridges. Although more than 4 major double tunnels have been designed (Dodoni, Anilio, S1 and S2 of section 5.2.3), bridge design is the Firm's most important contribution.

From 1996 to date the firm's involvement in bridge design covered three different types of services, namely: Complete design of bridges for Egnatia Odos S.A. or other Contractors, checking of designs produced by other firms, and general review of designs produced by others.
