I am inside a tunnel with distinct sodium-vapor lighting. The traffic is moving on the right side of the road, which is standard for most of the world. The tunnel walls appear to be made of rough stone or concrete, and the lighting configuration is quite specific. These types of tunnels are common in mountainous regions or urban areas with significant infrastructure. I suspect this is in a country with extensive tunnel networks.

I suspect this is in Spain, possibly near a major city like Madrid or Barcelona. I am not very sure yet.

then: forward

The tunnel's distinct double-row lighting pattern and the specific texture of the walls are characteristic of the tunnels found in the Canary Islands, specifically on the island of Gran Canaria. The road markings and the general atmosphere of the tunnel align with the GC-1 highway infrastructure. The sodium lighting is very typical for these older, long-established tunnels in the region. I am fairly confident this is located on the GC-1 motorway near Las Palmas.

I suspect this is in Spain, specifically Gran Canaria. I am reasonably sure.
