I happened to stumble upon this piece of info via Alexander Wurz’s Twitter account.
This was news to me, at least, I don’t know if you guys knew about it or not.
From what I can gather, I would be very surprised if they’d make the corner faster, especially that that’d still mean no run-off, so I think they must be working on a small strip of run-off area there by removing those garages that were stick in there, under the upper promenade, for decades.
That upper promenade now hosts the pit lane, of course, but it’s very interesting to see the upward slope of the road on the first pic – that ‘ramp’ was where the original circuit went up (they used to call it that way) before the layout took an early detour to the lower roads around the swimming pool beginning from 1973. Before that, cars swept up there then down the current pit lane in the ‘wrong way’ and connected back to the start/finish straight via the Gazometre hairpin at the far end that was about as tight as Loews.
In the same pic, one can also see the old stone handrail, kind of unearthed from behind the garages. (This section north of the swimming pool did not receive the enlarging treatment the lower section got in 2003.)
