The diverse terrain crossed by the Egnatia Motorway together with the special environmental conditions encountered imposed the construction of a large number of bridges with a combined length of 42 km (measured as single carriageway). This means that 6% of the road axis length runs over bridges, the construction cost of which corresponds to X% of the total motorway construction cost.

These structures are twin split carriageway bridges, in accordance with the practice followed in the construction of German highways.

The construction of such as variety of bridges demands the application of every possible modern construction method currently in use.
