Are there any pictures and maybe a map?

It's almost ten years since the one time I was in Bordeaux (for just 1 day).

That design... iconic, it is. Good choice!

uh? Would there be an observation deck up there? cause lazy or tired or simply regular folks won't use the stairs to go up. But they might be fun to go down like in the Eiffel tower.

Cool design. And I like those spiral stairs behind that glass. Though I imagine those tubes could heat right up from the sun unless that's double glass I see.

Nevertheless would an underwater tunnel not be a better choice here, as such a structure does not require any interruption of car traffic and can be passed by ships of any height?

Otoh a bridge can be used by pedestrians and cyclists - which is very important in/near the urban core.

There's some large redevelopment underway all around that bridge, on both banks if I'm not mistaking. This lately posted on the French forum caught my attention for example.

Brazza Nord Bordeaux Masterplan / KCAP

[...] The project site is a 67 ha area within Bastide Brazza Nord, a 120 ha former industrial area between the river Garonne and an abandoned railway area. The urban strategy will combine new urban mixed-use functions with re-used abandoned infrastructures and is based on an integrated environmental approach to ground pollution and flood risk. [...]

The program consists of about 600.000 m2 of housing, offices, industrial and public facilities and new public spaces to be implemented on the old industrial riverbank and the abandoned railway area. In the end of 2012 a new bridge – ‘Bacalan Bastide’ – will connect the right and left bank of the Garonne river. This connection will improve the relation of Brazza Nord and the rest of the city. It is considered as a key opportunity for the regeneration of the surrounding communities and will have an important impact on the entire region.
