I spotted those wires on the Dbayyeh highway right after Nahr el Kalb (if you are heading towards Beirut), and before the Canadian embassy on the maritime road. I also remember seeing one of those on the Dora highway but can’t remember where.
The one in Jal el Dib is connected to a small box on an electricity pole. They can’t be just random wires because they are well fixed on the ground.
First thought that occurred to me is that they are linked to some sensor that detects the number of cars passing by but I highly doubt the concerned ministry is using such equipment.
Does anyone have a clue what are those for?
