A woman whose teenage daughter was killed on a notorious seafront road says new plans for safety measures have come too late.

Councillors have approved a project to stop boy racers and speeding drivers who reach up to 100mph along Madeira Drive, Brighton, at night.

It is hoped new gates and speed cushions will stop further deaths and serious injuries.

But Betty Gregory, whose 17-year-old daughter Lynsey Richmond was killed, said Brighton and Hove City Council should not be praised.

She said: "I have been campaigning for speed humps there for six years. I am still very angry that it has taken this long.

"My daughter was killed because the driver was speeding.

"Had there been humps or speed cameras she would be here today enjoying her life and growing up.

"We feel that the council should get no credit for this."

Mrs Gregory set up the Madeira Drive Action Group and was joined by Pauline Jordan whose daughter, Harriet Jordan Wrench, was critically injured.

The group asked council leaders to take action after three fatal accidents and seven which left victims seriously injured.

Temporary barriers are currently put in place at night when car cruising events are planned. They have stopped nationally-organised events.

But they are only put up when it is known racers are on the way and erecting them is time consuming.

The city council's environment committee has approved two gates opposite the Colonnade and Duke's Mound but it is not known if they will be closed every evening or between which times.

It also agreed to install speed cushions at 75m intervals along the road, which can be taken up for events such as the speed trials in September.

The cost could be £100,000. A further £18,000 a year would cover running costs.

Tory councillor David Smith said: "This is a great opportunity to do something really good for Madeira Drive."

He hoped the calming measures could eventually be extended east to Black Rock.

Coun Gill Mitchell, who chairs the environment committee, said: "I am pleased we are in a position to do something."

Green councillor Georgia Wrighton added: "I should like to thank the group of parents who have worked so hard to prevent accidents."
