Cable-Stayed Bridges - Stonecutters Bridge (7)

A view of the transition from steel to concrete   on the back span of Stonecutter Bridge. I think this transition looks pretty good. The approach to this bridge on Tsing Yi Island goes through a maze of ramps and connectors before plunging into a tunnel.

You can see rails (along the inside edges of the steel box girders) that will carry a painter's traveller. There will be one on each back span and a third under the main span. A large crew will spend their careers keeping this bridge painted (and inspected for possible damage).

You can also see the much bigger cable anchorages on the concrete spans. These short back spans are balancing the long, main span and have to be carefully designed with stronger cables and a bigger anchorage assembly.
