That's weird. It definitely looks like it is the same bridge but that page says it has been removed.

The construction clearly shows a concrete bridge in the making (lots of concrete forms visible) whereas the heading of the page is 'Swiss timber bridges'.

as far as i understand it the timber bridge was the temporary bridge used to support the construction and then torn down after the concrete bridge was completed.

Ah yes, it's labelled 'falsework', so the wooden structure is indeed just to support the main structure until it can be self supporting.
