The Milkbeck Road's badly congested due to roadworks at the roundabout at Windscape Lane. The roadworks are a trench seven foot long. The congestion is caused by the traffic lights regulating the traffic flow around the roadworks. When the lights are on green to allow the Milkbeck Road traffic through the roadabout it's green in both directions. Which means that the priority traffic, nearly all of which is turning right onto Windscape Lane, is allowed through first. And the traffic heading for Becup stays stock still while it waits for the gap in the right-turning traffic which never happens.
It takes a special sort of genius to engineer that.
