Forest Road is closed in both direction due to a hazardous tree.
A car was in collision with a tree just west of Cottesmore School, Pease Pottage, at 3.15pm today(Friday December 13).
The incident caused the tree to lean on some power lines.
The road is closed until tree surgeons cut down the tree.
The person driving the car was not injured, said West Sussex Fire and Rescue.
