Just a bit of clarification, Waterloo roundabout is NOT closed, it is the road from the roundabout to Newmaiins? (1st on left coming from Wishaw) which is closed. Diversion via roundabout at Verve car sales I guess. Passed thro today.
Being a Well supporter for half a century and more, and living round the corner from Fir Park for most of the early years my memory of the stand being built in this fashion was because the owner of the house(s) needed to extend to the corner refused to sell to the club. One house at least would have had to be demolished.
