The bridge cost US$100m. [awayn]
"It is said that if a person falls from the Siduhe bridge it will reach terminal velocity, meaning that there is no acceleration, the body of the person is falling at a constant speed; this is the only bridge in the world where is possible such a phenomenon." [LookBridges]

| Highway Engineering Discoveries posted The Sidu River Bridge (Chinese: 四渡河特大桥; pinyin: Sìdù Hé Tèdà Qiáo) is a 1,222 m-long (4,009 ft) suspension bridge crossing the valley of the Sidu River near Yesanguan in Badong County of the Hubei Province of the People's Republic of China. The bridge was designed by CCSHCC Second Highway Consultants Company, Limited. and built at a cost of 720 million yuan (approximately US$100 million).It opened to traffic on November 15, 2009. |
This photo confirms that the east end goes directly into a tunnel, and this bridge is another example of short backstays because they are anchored to a mountian.

| AtlasObscura, GLABB/CC BY-SA 3.0 "This highest bridge in the world [Until the 2016 Duge Bridge] spans such a great chasm that it had to be established using rockets." Several sources have stated that the pilot line was carried across the valley using a rocket. One even said that a helicopter could not do it. But the source did not explain why it couldn't. Is it because the weight and lateral tension of the wire would be too great for a helicopter? |

Highway Engineering Discoveries posted Sidu River Bridge Suspension bridge , China Height 496m [I made this photo small because the post is rather obviously wrong. This is a photo of a different bridge.] Dennis DeBruler: I don't know which bridge is in the photo, but it is not the Sidu River Bridge. https://www.reduper.com/.../river-bridge/sidu-river-bridge/ Dennis DeBruler: I think the photo is of the Duge Bridge. |

reduper has three photos of the rocket. The first photo shows it was done near the completion of the towers. I'm trying to figure out how they caught the cable when it arrived at the far side.

They didn't use a cute box girder deck. They used an old-fashioned, heavy-duty truss deck.

I wonder how often often base jumpers use the bridge.

Just walking across the bridge would be enough excitment for me.

This gives a whole new meaning to the notion of a fear of heights: high above the world's highest (2009-2016) bridge deck.

This bridge is just the tip of an iceberg in terms of constructing G50 between Chongquing and Shanghai. Because of the tunnel entrance on the east side, I zoomed out to see what was happening.
I added a red line to indicate the location of the Sidu River Bridge. The yellow lines show the two tunnels in the area.

Here I zoom in on the concrete bridge that is on the east end of the western tunnel.

I presume this video is of that concrete bridge because it was in with the collection of photos for the Sidu River Bridge.
