A man and a woman died and another woman was seriously injured in a two car collision in Lydney on Friday afternoon in wet and windy conditions.
It happened at about 3.40pm at Lensbrook and involved a Peugeot and a Mitsubishi.
The two occupants of the Peugeot, a man aged 29 and a woman aged 46 both from Lydney, died at the scene.
A 72-year-old woman in the Mitsubishi, also local, was airlifted to Frenchay Hospital in Bristol with life threatening injuries and remains in a serious condition.
Road closures were in place for five hours while a full collision investigation was carried out.
Some residents living nearby have said the speed limit should be reduced.
One described the corner as 'not good' and said people use the road as 'a race track'.
But another resident said reconsidering the speed limit would not stop those who already break the law and speed there.
County councillor Alan Preest (UKIP, Lydney) said: “‘It is an awful road, a very fast road. It’s terrible that it has happened at this time of year and everyone has to take care at Christmas, whether that’s speed or drinking or drugs.
“Its notorious that road. Perhaps we need a lower speed limit but perhaps we need more policing out there on these fast stretches of road.
“It’s a very frustrating road because the way it is designed is for no overtaking and one of few places to overtake is between Blakeney and Lydney. Having police visible would urge people to slow down. I’m working with the county council to get some vehicle activated signs on the outskirts of Lydney and perhaps we need to get some on the approach too.”
Anyone who witnessed the collision but hasn't spoken to police should call 101, quoting incident 347 of December 27.
