A mother whose only son was killed at an accident black spot in North Somerset returned to lay flowers on the first anniversary of his death.

Sally Edwards paid tribute to 17-year-old Nathan at the junction of Providence Lane and the B3128 near Long Ashton on Thursday.

Signs at the junction are to be improved, and Mrs Edwards said she hoped it could prevent more deaths.

Mrs Edwards, 55, of Burnham-on-Sea, was driving Nathan, a talented tennis player, to the David Lloyd Leisure Centre.

She took a detour along Longwood Lane for the first time to avoid heavy traffic on the Cumberland Basin.

There have been several crashes at the busy junction, where Longwood Lane and Providence Lane meet the B3128, since Nathan's death on November 20 last year.

The crash happened as Mrs Edwards drove her Peugeot 405 estate along Longwood Lane towards Providence Lane.

She hit a Range Rover which was travelling along the B3128 near the junction of Providence Lane.

Nathan was pronounced dead at the scene while 10-year-old Corey Nichols, who was in the back seat the car, was seriously injured and taken to Frenchay Hospital.

Long Ashton Parish Council has campaigned for improved signing and white lining at the junction for years.

North Somerset Council announced this month it would install new larger signs at the junction with a yellow background to warn of the road ahead.

"The night of the crash was the first time I had ever used that route," said Mrs Edwards.

"I had no idea that the junction was ahead as by the time I saw the sign, I was already at the junction.

"The white lines on the road had also practically rubbed off.

"If better signing and lighting warning of the junction had been in place it could have well prevented this tragic accident from happening.

"This narrow country lane meets the busy B3128, which is a very fast road.

"I am glad the signage is going to be improved and hope it prevents further accidents.

"I would not want any family to go what I have been through."

Mrs Edwards also put up pictures of Nathan playing tennis, enjoying his birthday with friends and of him collecting the Somerset County Men's Singles Cup, which he won two months before his death.

"Nathan is on my mind 24 hours a day," she said.

"He was my only child and we were intensely close. You cope because in reality the truth is so incomprehensible."

Jess Budd, 17, who lives in Bristol, was Nathan's girlfriend at the time and had known him since they were 12 years old.

Miss Budd, a tennis coach at David Lloyd, also laid flowers.

"I think it is good news that the signs are going to be improved and hope it will prevent other accidents," she said.

Work to improve the signs is expected to be completed by the end of the month.

Long Ashton Parish Council chairman, Charles Cave, said: "The parish council has been pressing for better signage at this site as a matter of urgency before another serious accident takes place.

"I hope that the measures which North Somerset Council implement are sufficient to alert people that there is a major road junction ahead."
