Ghost, I've walked those bridges at El Chorro (dodged trains in the tunnels too). That place is a trip, huh? Climbing off of the Caminito, is freaking cool! Super airy!

We loved it. Good climbing, for sure, and we alternated climbing days with exploration days that were just as much fun.

Another walk-over only bridge, the Walkway over the Hudson (a re-purposed railroad trestle).

What about tunnels? They are similar in certain respects to bridges.
The engineers’ solution was pretty cool. They created hollow cement capsules, big enough to for BART trains to fit. They sealed what would become the entrance and exit to each capsule, and dropped the capsules into the bay so each sat next to another. Now they had a loosely beaded necklace strung from Oakland to San Francisco. To make they necklace strong they sealed the each capsule to the next. The only thing left was to chip away the entrances and exits and—voila—we have our trans bay BART tunnel!
The HSR tunnel requires large clearances around the train for aerodynamic reasons. Without those clearances, a high-speed train (going 1.5 to 2 times as fast as BART's maximum speed) will dump megawatts of power into swirling the air inside the tunnel, making it unbearably hot. In the diagram, the BART tunnel bore is 16 feet (5 meters), and the HSR tunnel bore is 26 feet (8 meters).
China plans to build the world’s longest underwater tunnel beneath the Bohai Sea by 2026, connecting the port cities of Dalian in Liaoning province and Yantai in Shandong province.

I don't know the story, but they seem to specialize in this sort of thing.

frumy's post ^^^ is of a bridge that has occurred to me a few times when considering the thread title. that it started like this ^^^ and turned into this: 800 miles up the (being constructed at the same time) AK hiway by soldiers in response to japanese aggression,
makes it cool beyond it's mere impressiveness. nisutlin bay bridge near teslin, yukon territory
