A closer look
Imagine starting your journey driving across a bridge, sky above and sea beneath you, only to find the road suddenly plunging into the water and transforming into a tunnel. It sounds like a magic trick, but it’s clever engineering in places like Denmark and China. This design allows ships to glide safely above while cars zip quietly below, combining the breathless view of a bridge with the hidden adventure of a tunnel. It's as if the roadway can’t decide if it wants to soar or dive—so it does both. What looks like sorcery is actually a genius solution to fit two worlds—the one on the surface and the one beneath—into a single line of travel.
