Main Square car park has been sporting this sign since earlier this week.
Inside the car park, when we were there a couple of days ago, was a second sign saying that work was in progress on the top floor. So, donning our oxygen mask, we went up to the roof at the end of the afternoon. Where there was nothing to see – not even a parked car.
Maybe the work is to repair the expansion joints in the concrete floor? We wrote about this nearly a year ago. http://wp.me/p3Dlu2-1VU
