V Festival traffic delays at A5 near Weston Park

Delays of two-and-a-half hours were reported

People travelling to the V Festival in Staffordshire have faced long traffic delays, the Highways Agency said.

Its website reported delays of two-and-a-half hours on the A5 earlier from Cannock to Harpenden, between the junctions with the A4601 and the A449.

The event, now in its 17th year, is being held on Saturday and Sunday at Weston Park, on the Shropshire/Staffordshire border.

Revellers were advised by police to plan their journeys to avoid delays.

Happy Mondays

The Highways Agency said about 25,000 vehicles were expected to head to the festival area, and by about 19:40 BST the vast majority of these had arrived.

The northbound exit at junction 12 of the M6 was closed on Friday until lunchtime, with festival traffic diverted off the M6 at junction 10A on to the M54.

Southbound traffic on the M6 was able to leave at junction 12, the agency said.

Earlier, Supt Pete Owen, from Staffordshire Police, said: "The roads around Weston Park were not built for and not designed for a festival of this size.

"People have got to be patient. They've got to queue."

The V Festival is also held at Weston Park's sister site, Hylands Park in Chelmsford, Essex.

The Stone Roses, Happy Mondays and The Killers are among headline acts.

Paramedics at Weston Park will this year use an all-terrain vehicle to reach anyone needing medical help.

An estimated 85,000 people are expected to attend the event in Staffordshire each day.
