Just been monitoring the traffic. 21.00 till 22.00 This is what I have witnessed.
HGV Traffic heading for B’ham are taking the eastern avenue bypass the diversion route. Which is logical.
It appears that HGV Traffic that want to proceed to the A5 towards Cannock are not taking the diversion route and are proceeding down from the Eastern avenue/ A51 junction near the Hedgehog restaurant straight on towards the Bowling Green Roundabout. This is where some HGVs take the Sainte Foy Route towards the A5 Muckley corner ,others are taking the Walsall road through Leomansley. So they are going to get it for the next 3 weeks !!
