Lights needed for safety
In March 2015, the lights were turned back on as part of a £750,000 repair scheme.
They had been switched off that January while workers carried out repairs on surrounding roads.
The Highways Agency (now Highways England) said the signals were then replaced with an updated set to reduce the need for future emergency repairs. At the time, a Highways Agency spokesman said: “The traffic lights are needed to help increase the capacity of this busy roundabout, and are being replaced to ensure the junction continues to operate safely and efficiently.
“Without them, the safety and capacity of the roundabout would be reduced.
