Mitton Street works - time to weep

Just come through town and they've cordoned off the right-hand lane of Mitton Street just off its entrance, no idea why and there's nobody about. That's not the cause of my weeping though.

Despite the fact that there's a bloody huge sign at the left-hand continuation from Worcester Road into Mitton Street telling everyone the right-hand lane's closed; despite the fact you can see from the corner that the right-hand lane is closed; despite both those facts traffic is still stopping at the left-hand entrance lane from Worcester Road to let the traffic from Gilgal come down and change lanes.

Seriously what is wrong with you people?

[Update - it was moved last night, but all the barriers were still stacked up on the side]
