Temporary traffic lights blown over in strong gales are causing traffic chaos on the main road into Newquay.
Devon and Cornwall Police are currently on the scene directing traffic.
Meanwhile Cornwall Fire and Rescue Service are said to be examining the batteries of the toppled traffic lights after they started to smoke.
Both the emergency services were called to the scene at around 4.30pm.
It is not yet known when the lights will be fixed but traffic queues are expected to last for quite some time.
