Traffic arrangements due to heavy maintenance works on the Northern Branch of Patanos Tunnels

As part of the heavy maintenance campaign on the Motorway, the old analog cameras in the northern branch of T15 Tunnels (Platanos) will be replaced with new digital ones from Tuesday, February 3, 2026 to and including Thursday, February 19, 2026. 

To implement the above works, the closure of the branch to Patras and the diversion of the traffic to the tunnels service road located north of them, is required in accordance with the following diagram. The traffic in the direction to Athens is not affected.

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.
