POLICE and councillors are calling for an urgent investigation into whether one of the region's most notorious accident blackspots should be widened into a dual carriageway.
At least six people have been killed and 20 seriously injured in more than 63 accidents on Southport's scenic coast road, in the last three years.
Residents now fear the accident rate could rocket after resort bosses announced a £50m plan to boost visitor numbers with a host of new attractions by 2008.
But the plan - which incudes a five-star hotel and conference centre, and the North West's biggest indoor ski dome and aqua park - does not budget for improvements along the coast road.
Last night, police revealed that they were actually powerless to enforce an existing 50mph speed limit on the Formby to Southport route.
The picturesque five-mile road is buffered on either side by sand dunes, making it too narrow for officers to pull motorists over.
But a recent traffic services report found reducing the speed limit was "not justified", after surveys showed average top speeds were between 49.9mph and 54mph.
Local police and councillors in Ainsdale and Dukes are now calling for an urgent meeting with Sefton officials in the New Year.
Inspector Steve McNaughton of Ainsdale police has been meeting with local councilllors to thrash out possible solutions.
He said: "We have had a continuing problem with crashes resulting in fatalities and serious injury on this road for a number of years and something has to be done.
"We need to sit down with the council and look at all the options - and that includes everything from turning it into a dual carriageway to putting in new street lighting.
"There is really no reason why we should not be able to pull people over, the council could easily carve out some little lay-bys in the sand dunes.
"It is just a question of deciding what the best strategy is and then we can look at what funding we can tap into."
The council has already removed a dangerous fence after Lana Gittens, 28, was killed in May at the same spot where Mario Campagnuolo, 58, died five years earlier.
Inquests heard both drivers were impaled by horizontal slats in the wooden fence after they lost control on a straight stretch between Liverpool Road and Pinfold Lane, Ainsdale.
Tory councillor Brenda Porter, spokeswoman for Ainsdale and Dukes ward area committees, said: "It's outrageous that no provision is being made to improve safety along the coastal road.
"We must not wait until someone else dies to do something about it."
