AizhaiAvatarCanyon.jpg

Looking like a scene from the movie Avatar, the deep canyon dwarfs one of the towers in the upper left.


AizhaiBridgeView.jpg

The view from the side with the short tower shows the taller tower halfway complete on the far side of the canyon. Image by www.smxxsy.com


AizhaiShortTower2.jpg


AizhaiShortTower.jpg


AizhaiFoundations.jpg


AizhaiTowerDesigns.jpg

Several Aizhai bridge tower designs.

AizhaiAnchorage.jpg

One of the cable anchorages located on the back side of the mountain range.



AizhaiRoad.jpg


AizhaiWindTests.jpg

Aizhai valley wind test model.


AizhaiSaddle.jpg


AizhaiAnchorage2.jpg

Note how close the foliage is to the back span cables.


AizhaiCatwalk2.jpg


AizhaiBackSpan.jpg


AizhaiTunnels.jpg

The tunnel entrances beneath the tall tower.


AizhaiCableView2.JPG

One of the cables sagged down into the gorge during the early process of setting up the catwalks. The Chinese workers quickly freed up the cable and hoisted it out of the valley.

You can view a video here of the preparation to use a small blimp to take the first pilot line across. http://bbs.rednet.cn/thread-22618784-1-1.html


AizhaiCableView.JPG

AizhaiCableView6.JPG

The hanging cable reveals just how high up the scaffolding is below one of the towers.


AizhaiCableView7.JPG


AizhaiConstView3.JPG


AizhaiCables5.jpg


AizhaiCables.jpg

The catwalks were in place by mid-2010.


AizhaiCableSpinning.jpg


AizhaiCableSpinning2.jpg


AizhaiCableSpinning3.jpg


AizhaiCablesComplete4.jpg


AizhaiCablesComplete.jpg

The main cables were completed in the fall of 2010.


AizhaiCablesComplete2.jpg


AizhaiCablesComplete3.jpg


AizhaiRenderinfg.jpg

Aizhai computer rendering. In the final design, the taller tower was built with a horizontal cross brace.


AizhaiConstProcess.jpg

A large model was created to show the unique process where the truss sections will be pulled and rolled along hanging cables with wheel bogies attached to them.


AizhaiModelTruss.jpg


AizhaiConstProcess2.jpg

One of the massive bogies especially designed to pull the suspended truss sections out over the gorge.


A test section was set up for the traveling bogies. The temporary supports simulate the stringer intervals where the bogies will travel on cables that are connected to the ends of the stringers.


AizhaiBogie.jpg


AizhaiBogie2.jpg


AizhaiNight.jpg


AizhaiNight2.jpg


AizhaiNight3.jpg


AizhaiRendering.jpg

The most recent rendering showing the final design with pointed ornamentation on the tower tops.


AizhaiBridgeDrawing.jpg


AizhaiBridgeImage3.jpg


AizhaiBridgeImage2.jpg


AizhaiBridgeImage.jpg


AizhaiDrawing.jpg

An earlier drawing showing a blue pin stripe paint scheme.


AizhaiAreaMap.jpg

Map of the new highway northwest of Jishou.


AizhaiPropMap.jpg

A map showing the various Aizhai bridge routes and proposals that were studied.


AizhaiProp1.jpg

Aizhai bridge proposal 1 would have required an unusually long main span of 1,300 meters and a lengthy side span but both towers would have been short.


AizhaiPropC.jpg

Proposal C would have had a main span of just 1,100 meters and is similar to the final design.


AizhaiPropM.jpg

Proposal M would have had a main span of 1,228 meters but required a tower almost 200 meters high as well as an anchorage resting on a steep mountain slope.


AizhaiPropQ.jpg

Proposal Q is very similar to the final design but with a slightly shorter main span of 1,128 meters.

Aizhai and Royal Gorge bridge size comparison
