Traffic arrangements due to heavy maintenance works in Mavra Litharia Tunnels

In the context of heavy maintenance of the motorway, works for the replacement of old luminaires with LED luminaires in the T11 twin tunnel (Mavra Litharia) and for the re-coating of its side walls will be carried out starting on Friday, September 27, 2024.  In order to carry out the above-mentioned works, it will be necessary to close the tunnel branches alternatively, while the necessary traffic arrangements will be gradually implemented in the following phases:

Phase A: closure of the branch to Patras

Closure of the branch to Patras and diversion of the traffic to the tunnel service road located north of them, in accordance with diagram A.  The traffic in the direction to Athens is not affected.

Phase B: closure of the branch to Athens

Closure of the branch to Athens and diversion of the traffic to the branch to Patras through the Emergency Openings located at k.p. 143.30 to k.p. 141.30, in accordance with the following diagram.  The diversion of the traffic to Patras is still in place, as per Phase A. 

 Phase B: closure of the branches to Patras and to Athens

Closure of both traffic branches in the direction to Patras and Athens and diversion of both of them outside the Mavra Litharia Tunnels, in accordance with  diagram C.

The required long-term signage will be implemented according to the above sequence of the appropriate Phases, beginning on Friday, September 27, 2024 through Friday, October 25, 2024, at the latest. It is estimated that 2 weeks will be required to implement each of Phase A and B, while Phase C will take approximately 1-2 days. It should also be noted that as each Phase of works is completed, the next Phase will begin immediately.

Olympia Odos would like to thank the drivers for their understanding and invites them to comply with the relevant signage and the instructions of the Traffic Police, as well as to be particularly careful when crossing the said area.
