The A27 around Chichester is already heavily congested, particularly coming from the west to the Fishbourne Roundabout and east along Arundel Road where motorists are queueing for the turnoff to the festival.
There are currently no reports of accidents and through the city of Chichester, traffic appears to be moving freely.
Elsewhere there are no signs of any major accidents or road closures affecting motorists (as of 9am).
On the trains, a ban on overtime work for drivers continues to disrupt some services, and there are a number of engineering works taking place over the weekend, including between Redhill and Horley, and Brighton and Lewes on Sunday morning.
