Safety barriers may be installed at the scene of a crash which killed a popular West Sussex deputy headteacher.

The move comes in the wake of growing demands for more safety measures on the busy A24.

A £240,000 scheme to install barriers between Ashington and Washington is due to start this year following a campaign by widow Caroline Dey. Now the work could be extended after the crash at the Buck Barn crossroads, near West Grinstead, on Wednesday which left two women drivers dead.

The crash claimed the life of 53-year-old Sonia Bartlett, deputy head of Millais School at Horsham, and Kirstie Masters, who was in her 20s and lived in Uxbridge, Middlesex.

Mrs Bartlett, who was driving a Ford Escort, lived at Beaumont Park, Littlehampton, with her husband, Hugh.

Today a spokesman for West Sussex County Council said the cause of the crash which killed the women would be investigated by experts from its highways department.

He said: "With every fatal accident we go out to the site to work alongside the police to try and find out what happened.

"We will look to see if there are any safety aspects that could avoid something like this happening again.

"However, to do the whole of the A24 would could cost millions of pounds and we cannot pretend that finance does not play a part."

Mrs Dey, 29, of Slinfold, near Horsham, celebrated victory this year after getting barriers installed on the road where her husband was killed. She launched her campaign after the crash on the A24 at Ashington.

Her husband Barry, 29, died when a car crossed the central reservation and crashed into his estate car in May.
