Supporters gathered for a rally as part of an ongoing campaign to keep an area of King’s Lynn traffic free.
Last Saturday’s rally was held at the south end of Hardings Way to voice concerns about part of a blueprint plan which protestors fear could see up to 100 buildings go up along Hardings Way.
The organisers held the event to coincide with West Norfolk Council asking for public feedback on the Local Plan.
The campaigners hope the plan will be amended to remove Hardings Way and Hardings Pits in South Lynn from the list of areas designated for potential development.
Protestors say housing immediately alongside the nature area of Hardings Pits would have an adverse effect on wildlife and destroy the character of the open rural atmosphere.
More than 1,500 people have signed an online petition launched by Kevin Waddington to “Keep Cars off National Cycle Route 1 in King’s Lynn”.
Mr Waddington said he spoke to around 30 people at the rally about what it could mean for Hardings Way if homes were built.
“There would be HGVs coming and going during construction, and there would have to be access permanently for residents.
“This would mean that the current rural atmosphere would be destroyed and Hardings Way, currently a safe haven for cyclists, walkers and children on the way to Whitefriars school, would no longer be so,” he said.
As a symbol of their concern, campaigners also tore up mock copies of the plan and put them in a black bin, which they dubbed The Dustbin of History.
Councillors Alexandra Kemp and Michael de Whalley attended the rally along with representatives of Harding’s Pits Association.
Mr Waddington said most members of King’s Lynn Bike Users Group (BUG) were unable to attend but sent a message of support.
