Now that's a late night gig. I've never heard of that before. Personally its a bit too late for me, i'd be falling asleep during it but that's an age thing. 😂
They do the same in Glasgow area with the motorways shut down completely after 11pm on a Sat for repairs. Some of the detours have taken me an hour just to get back on the motorway again. A journey that normally takes me an hour to get home takes me 2 hrs.
