Ah ha...I think I agree...I'm coming from Castle Brom and work down Hagley RD. This morning it looked like it was doing exactly as you suggested. I didn't follow it's route because I expected the A4540 ring road to be faster and more familiar to me, I also had an early meeting I didn't want to risk missing. Tomorrow when I don't have specific time commitments I shall follow the Waze route and see how well it worked.
Cracking stuff...thanks to whom ever closed the tunnels...much appreciated
I presume the closure will re-route in both directions, maybe I'll test that tonight! Not 100% sure, but, I think they've closed off one end of Broad St so even if you aren't intending to use the tunnels, travelling Hagley RD to Broad St to....other side of city may not give access to surface routes...I'll report back!
