National Highways has said that it is investigating the ongoing 'issue' with the traffic lights on Kemplay roundabout.
The 'issue' with the traffic lights on Kemplay Bank roundabout has led to the lights 'changing too soon' back to red, leading to substantial disruption to traffic in and around Penrith.
The traffic lights are operating, but are changing too soon, meaning fewer vehicles are moving through before they turn red leading to tailbacks on the A66, M6 and A6.
National Highways has said that it now working to find a solution to the issue 'as a matter of urgency'.
A spokesperson National Highways said “As we enter the weekend, we appreciate this may cause additional disruption to journeys and apologise for any inconvenience”.
"Please bear with us, fixing the lights as soon as possible is our top priority”.
