Traffic on the A17 may be brought to a standstill with Sutton Bridge villagers threatening a mass protest in their cars.
Sixty or more cars could take part in a 5mph drive in the protest against a £165million gasifier.
The protest takes place on Saturday, July 26 – the first weekend of the school summer holidays – and is expected to cause massive disruption.
Great grandma Shirley Giles (74), who used her own cash to scupper planning consent given to EnergyPark Sutton Bridge for the gasifier, is ready to fight in the courts again if South Holland District Council passes amended plans. A council decision could come as early as July 30.
Mrs Giles said a new body called The Wash and Sutton Bridge Protection Group is organising the 5mph drive on a loop taking in two A17 roundabouts.
She said: “We have got 60-plus people on a mailing list – I don’t know how many will turn up – but people can walk up and down Bridge Road with placards as well.
“I don’t mind women with pushchairs walking up and down with placards. It’s there for everybody to come up and be counted.”
Mrs Giles and fellow parish councillors Jenny Rowe and Vicky Hills collected hundreds of signatures last weekend on a petition against the gasifier – and will be out with their petition again at the top of New Road between 10am-4pm on Saturday and Sunday.
The village will have 17 towering chimneys, including two at an existing power station, if the gasifier and a new gas fired power station are built.
Mrs Hills said: “I would just like to say we are the gateway to Lincolnshire, not the dumping ground for Lincolnshire.”
Sutton Bridge Parish Council wants a planning inquiry to decide if the gasifier can be built and has the support of South Holland and The Deepings MP John Hayes.
Mr Hayes said: “I have a very simple view of these things. I ask ‘would I want it next to my house?’ – if the answer is no, then I wouldn’t want it for anybody else.”
