This is the tunnel that leads from street level underneath the business district to the underground station. It's only open for a couple of hours on working days for the commuters to use. The local transport company have installed coloured lights which are constantly changing, they're great and make the tunnel so bright.
I was in the city centre at the right time today so thought I'd go and photograph it, I think I was getting in the way of the commuters though, they were all in such a rush to get to the station.
