Road closures have been put in place on the southbound A41 at junction 5 of the M1 and the north bound exit of junction 5 of M1.
Delays are likely to remain for a couple of hours and are expected to happen again around midnight in Watford and the surrounding areas as people leave the festival. Motorists are advised to avoid the area if at all possible.
