AROUND 300 letters have been handed in to the council from residents who oppose the redevelopment plans at Royston High School.
Royston councillors Graham Kyte, and Tim and Tracey Cheetham handed in the objections at the planning offices on Wednesday.
Kier Property Developments submitted a planning application for 143 houses, a supermarket and petrol station on the site.
It also includes car parking space, landscaping and an outline application for a health centre.
The council-owned land - thought to be worth around £7m - has long been a topic of conversation on We Are Barnsley. Many of you have opposed as there are three supermarkets in Royston and a petrol station already.
''These letters represent the tip of the iceberg as far as objections are concerned,'' said Cllr Kyte. ''Another supermarket and petrol station are not needed or wanted in Royston.''
Fred Harston, chairman of Royston Tenants and Residents' Association, said one of the biggest problems would be an increase in traffic.
"There will be 143 houses going up, which could mean up to 300 cars if families have two cars,'' he said. ''The road structure was not built to take that kind of traffic. Its already tight on Midland Road when cars are parked on each side of the road.''
