So seemingly, they put the sign up before I parked -- meaning it was dark and I mistakenly expected the previous (removed) sign that only covered a single bay.
However, I did park there before the suspension started (i.e. I parked Friday 22nd), but did not expect to be stuck indoors with Covid as I only tested positive the following day.
So, the contractors (who have been working since before any suspension) are still there, requested two to three bays - but four were given and only one is actually being used for their equipment.
I guess I need to rely on the goodwill of them knowing I had covid.
