UPDATE 09.45am The A394 has now been cleared following an earlier accident. Traffic disruption is still being reported around Culdrose.
The main road between Helston and Falmouth was blocked in both directions this morning after an accident in the icy conditions.
The A394 at Wendron near the Trevenen turn-off has been blocked for at least the past half hour.
An earlier accident involving a motorcyclist near Culdrose Airfield has also led to the A3083 being partially blocked with "hazardous driving conditions" reported.
Drivers are advised to avoid both areas and take alternative routes wherever possible.
Cornwall councillor for Helston South and Porthleven, Andrew Wallis, took to Twitter at 8.34am to report the accident on the Culdrose road adding: "traffic gridlocked in and around Helston."
