Sidu River Bridge is located in Badong County of the Hubei Province of China. Opened in 2009, the Sidu River bridge (which crosses the titular river, as one might expect), beat out the previous record-holding span, the Hegigio Gorge Pipeline Bridge in Papua New Guinea, which is suspended just over 1,200 feet above the ground. The Sidu bridge was part of China’s ever-expanding highway system, connecting two disparate parts of the country that were previously separated by difficult, mountainous terrain and multiple rivers. The bridge spans just over 5,000 feet across the river valley and was so far across that the builders had to use a rocket to string the first pilot line across the gap. The hefty length is supported by two massive, H-shaped towers, one at either end of the road. The suspension lines dip in the middle and rise back up again, looking more than a little flimsy for such a massive span.
