I am flying through a tunnel with distinctive orange-yellow walls and bright white overhead lighting. The traffic is moving on the right side of the road, which is standard for much of Europe. The markings on the road and the tunnel structure look very clean and modern, typical of high-quality infrastructure in a wealthy European country. I suspect this is in Germany, possibly in a major city like Hamburg or Berlin, given the tunnel design. I am moderately sure of this location.

then: forward

The bright orange-yellow walls of this tunnel are iconic and highly characteristic of the Elbe Tunnel in Hamburg, Germany. The traffic continues to move on the right, and the overall tunnel architecture matches the specific design of the Elbtunnel. I can see the distinct lighting pattern and the emergency exit doors that are standard for this major infrastructure project. I am very confident this is the Elbtunnel in Hamburg.
