The Longest A2 Egnatia Motorway Tunnels
The diverse terrain crossed by the Egnatia Motorway together with the special environmental conditions encountered imposed the construction (provision for) 74 twin-bore road tunnelsof an overall combined length of 100km (measured as single carriageway) measured at 50km of single carriageway. This means that 7% of the road axis length is carried through tunnels, the construction cost of which corresponds to X% of the total motorway construction cost.
