Drivers need to plan ahead to avoid disruption and disappointment when the seventh Latitude Festival kicks off this week, organisers have warned.

More than 35,000 people are expected to be heading for Henham Park, near Southwold, on Thursday for the four-day festival featuring Bon Iver, Elbow and Paul Weller.

But organisers Festival Republic are working closely with Norfolk and Suffolk police, and Suffolk County Council Highways, to develop a traffic management plan to ease congestion.

Road users have been advised to allow extra time for their journeys, or use alternative routes, to avoid the heavy traffic when people travel to and from the festival on Thursday, Friday, and Monday.

The A12 and the A145 near Henham Park will be busy, with peak traffic expected on the A12 northbound and the A145 southbound during late Thursday morning and afternoon, and Friday morning.

Most traffic is expected to leave the site late on Sunday evening and before noon on Monday when traffic will be heavy on the A12 in both directions particularly southbound and the A145 southbound.
