Sandringham: Van Morrison Robbie Williams The Who traffic

Superstars Van Morrison, Robbie Williams and The Who drew an estimated 80,000 fans to Norfolk's Royal estate for four nights of open-air gigs over the Bank Holiday weekend.

But both people living around the site and gig-goers were caught in congestion, as roads became grid-locked.

Giles Cooper, managing director of promoters Heritage Live, said: "After all concerts, Heritage Live and regional stakeholders gather and discuss every aspect of our operation, including traffic management.

"Whilst we love the large amount of praise we’ve had in every area of these concerts this year, we’re also a company that listens and we’ll act on constructive criticism and make every effort to improve what we deliver year-on-year."

Organisers had earlier warned people to allow two hours to get onto and off of the site before and after performances.

"It was chaos getting off the park after the show," said one man who lives in Dersingham and attended Sunday's Robbie Williams show.

His wife added: "You had 20,000 people at the do who'd been filtering in all afternoon, then at 11pm you had 20,000 people all trying to get off at once."

Jane Hankinson posted on Facebook: "From King's Lynn yesterday three hours in and another three hours to get out."

Charlotte Trenowath added: "Now 1.45am - stuck in the Sandringham traffic and didn't even go to the concert."

Mr Cooper said the weekend's shows were "just the first of a five-year planned series of all-day events" which would bring "world-class music" to Norfolk.

Minor roads around the Royal estate were closed, while long tailbacks grew along the A149 between Lynn and Hunstanton and A148  Lynn - Fakenham roads.

No right turns allowed off the west-bound A148 at Hillington, with drivers told instead to continue to the Knights Hill Roundabout, and perform a U-turn there before turning off for event parking.

Those heading north up the A149 from King's Lynn were also not allowed to make a right turn onto the B1439 Lynn Road, being told to continue to Dersingham roundabout and make a U-turn there.
