The A1067 is currently closed in both directions after a telegraph pole fell onto the road during the strong winds this morning.
It is closed in Guist, near Fakenham, with a police crane on the scene attempting to lift the pole.
Power workers are also at the scene.
A signed diversion is in place but officers are urging drivers to avoid the area as there are already long tailbacks.
Police were called to the incident at 7.50am (August 25), with the crane reaching the scene at 8.45am.
