I am currently inside a tunnel with white tiled walls and distinct blue lights along the sides. The road markings are white dashed lines, suggesting right-hand traffic. The tunnel's architecture and lighting style are very characteristic of modern European infrastructure. Given the visual style of the tunnel, I suspect this is in a major city in the Netherlands or Belgium. I am moderately sure this is in the Netherlands.

then: forward

The tunnel features green chevron signs on the walls, which are very common in the Netherlands for indicating emergency exits or lane guidance. The clean, modern white-tiled construction is typical of major Dutch tunnels like the Coentunnel or the Zeeburgertunnel in Amsterdam. I am driving on the right side of the road. I am confident this is in the Netherlands, likely within the Amsterdam ring road area.
