Cable-Stayed Bridges - Stonecutters Bridge (3)

I'm standing on Tsing Yi Island looking east across Rambler Channel toward Kowloon, just north of Hong Kong Island. Yesterday, I said that the steel structure attached to the tower was a rack and pinion elevator, but in this photo it's pretty clear that it supports the tower crane.

Note the winches at the ends of the cantilevered spans. Barges bring the superstructure segments into position where they're lifted up by the winches and hung from the towers with cables.

The two steel box girder sections are held apart by long steel floor beams. The openings between the steel boxes give the bridge a nice appearance but I'd worry about someone falling through the deck!
