10. Brave Men’s Bridge, Hunan Province, China
As if the 600 ft. height over the valley wasn’t terrifying enough, they went and made this suspension bridge out of plexiglass. It feels like you’re walking on air and about to plummet every step you take. The fact that you simultaneously sway with the wind doesn’t help matters.
11. Millau Viaduct, France
Leave it to the French to do horrifying with style. Running across France’s River Tarn, the Millau Viaduct runs more than a mile and a half across a massive gorge. “A cable-stayed, masted structure, the bridge is delicate, transparent, and has the optimum span between columns. Its construction broke several records: it has the highest pylons in the world, the highest road bridge deck in Europe, and it superceded the Eiffel Tower as the tallest structure in France.”
12. Lake Ponchartrain Causeway Bridge, Louisiana
At a staggering 24 miles long, the Lake Ponchartrain Causeway Bridge holds the Guinness Record for longest continuous bridge over water in the world. It’s reputation for unnerving drivers heading north out of New Orleans is widespread. Though it’s held up by 9,500 concrete pilings, that hardly seems like enough.
