Looking like a scene from the movie Avatar, the deep canyon dwarfs the north tower in the upper left.

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

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.

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

The catwalks were in place by mid-2010.

[[File:AizhaiRenderinfg.jpg|750px|center]]
An Aizhai computer rendering.  In the final design, the taller tower has a horizontal cross brace with more ordinary antenna-like tower tops.  The tunnel was also changed and does not extend under the taller tower.


[[File:AizhaiConstProcess.jpg|750px|center]]
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.

[[File:AizhaiConstProcess2.jpg|750px|center]]
One of the massive bogies especially designed to pull the suspended truss sections out over the gorge.


[[File:AizhaiBogie图为矮寨特大悬索桥试验现场.jpg|750px|center]]
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.

[[File:AizhaiPropMap.jpg|750px|center]]
A map showing the various Aizhai bridge routes and proposals that were studied.  


[[File:AizhaiProp1.jpg|750px|center]]
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.


[[File:AizhaiPropC.jpg|750px|center]]
Proposal C would have had a main span of just 1,100 meters and is similar to the final design.


[[File:AizhaiPropM.jpg|750px|center]]
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.  


[[File:AizhaiPropQ.jpg|750px|center]]
Proposal Q is very similar to the final design but with a slightly shorter main span of 1,128 meters.
