An official seaside invasion of motorbikers could lead to ' organised chaos'.

That was the response from a council events manager in Great Yarmouth after he was made aware of a bikers event which has been shared on Facebook.

On Saturday, July 8 5,000 bikers are expected to descend on the seafront in the second event of its kind and give a boost to the town's economy with the support of borough council traffic measures.

Last April the first 'Great Yarmouth Motorcycle Takeover' attracted over 3,500 bikers.

The event led to traffic jams and a parking 'free for all' according to a report seen by Great Yarmouth Borough Council's economic development committee.

The council's events manager David Helsdon said with the right planning, some of the challenges of last year could be overcome.

He added: 'I fully expect to have two hours of organised chaos as the bikes arrive on site.

'However with our involvement the event will be handled professionally which will go a long way to reassure residents and traders.'

Despite the traffics issues, last year's event passed safely.

Estimates suggest each visitor will spend £30 each meaning traders can expect a boost in the region of £145,000 on the day.

It is part of the annual Wheels Festival held on the same day in the town.

Plans for managing the event include closing Marine Parade from the Jetty Car Park to the Marina Centre Car Park North, to hold 3,500 bikes, with emergency vehicle access maintained.

The South Marina Centre car park will be closed and the Sea Life Centre Gardens will be used as a trade stand area.

Bikers would be asked to arrive between 10am and noon. Signs and marshals would direct them to the seafront from the south.

There are plans for convoys from as far as Huntingdon and King's Lynn.

A spokesman for the borough council said: 'We are working closely with the organisers of the visit and Norfolk Police to put together a plan to ensure that the visit happens in a co-ordinated way which reduces the impact on other road users, while still capturing the huge economic benefits the thousands of visitors bring to the borough.'

In a message posted on Facebook, the events' organisers said they had amazing support of the local authorities and added they will be raising money for the East Anglian Air Ambulance.

The message said: 'We've had outstanding support from the local authorities and have worked closely with them to ensure all possible problems are ironed out in advance.

A lot of other seaside towns have an annual bike meet, and we've always wanted to bring one to the town. People are coming from all over, from as far as Scotland and Ireland.

'We've attended meeting with the council, tourism board, and Norfolk police and covered all areas of safety and planning.

'We have detailed plans to route traffic to the seafront to avoid disturbing local traffic, marshals on the day to direct bikes and sourced off road parking to avoid taking parking from cars on the day.

'Last year, one rider crashed on his way to the event and the Air Ambulance saved his life, so this year we've decided to raise money for them as a thank you. Air Ambulance volunteers will be there on the day with collection buckets and event merchandise will also be available with ALL profits going to the air ambulance.'
