David Wynn has lived in Kootingal for a decade and is often the first on the scene when collisions happen where Sandy Road, Porcupine Lane and the New England Highway meet.

"It's terrible - we hear the bang, we hear the skid, we rush down and we never know what we're going to be coming down to," he told the Leader.

"Whether we are going to be picking up body parts, or whether we are going to be here nursing people as we wait for ambulance and police."

A safety upgrade to the intersection was finished earlier this year, as part of an $8.5 million plan to improve the stretch between Sandy Road and Moonbi.

Mr Wynn claimed there had been a noticeable increase in the number of serious crashes since the majority of the works were completed, the latest on Monday when four people were hospitalised and a car flipped.

"We've had numerous minor accidents and near-misses, and these occur on a daily basis," he said.

"I certainly believe we have not seen the worst at this intersection yet, that there will be a fatality here and unfortunately families are going to be ripped apart.

"All of the residents around the intersection are concerned ... about the volume of accidents that are here."

The highway speed at the intersection is 100km per hour and give way signs are in place on Sandy Road and Porcupine Lane.

Mr Wynn said he had taken his grave concerns to Tamworth MP Kevin Anderson and Transport for NSW, but said responses had been "non-committal".

A statement from Mr Anderson's office to the Leader said he had escalated community concerns to the minister for regional transport and roads.

Transport for NSW said in a statement community consultation was carried out for the project, as well as a traffic analysis and safety audit.

It said the authority would continue to investigate further safety improvements.
