Over the last 3 weeks there have been incidents including accidents on the approach to J14 South Bound

There seems a lack of signage to establish that the junction of the services and J14 there only cones that suddenly disappear for both locations. I think this causing excessive braking thus causing the incidents resulting in a 2 HR delay due to lane closures on 03.01.2021 as well as a similar requirement on 27.01.2021 in exactly the same place!!! Im no expert but there is obviously something wrong with the road plannimg during the upgrade works....
