I think it was light grey - it was put down just before I stop flying with LH sometime in 2008. I was informed Pier B was sort of refurbished a bit like to Gate 12 area was done up. As for airbridges, I was also informed that all T1 airbridges were going to be installed but due to finances, it was just gates 31 & 32 that were having them. Well Pier B was meant to be re-built a few years ago but with the recession and now with the state of the worldwide economy I can't see it happening again. The pics I saw were nice, a taller building with airbridges on the east side too (gates 1, 3, 5, 7, 9 and what was 11 is now 15).
