A Hertfordshire woman's campaign calling for immediate safety improvements to the A505 now has thousands of supporters.
There are fears that unless something is done to close off what she calls 'dangerous junctions', then many more drivers will be killed or injured.
Lynsey Langdon's husband was seriously injured in a crash between Royston and Baldock.
"Someone pulled out on him who was using one of the many dangerous slip roads on the A505 and she didn't have time to get across and he hit her and he ended up on his roof with two broken vertebrae."
The support for Lynsey's campaign has grown so much that she now has the backing of the local newspaper.
In the last couple of weeks it has been inundated with stories of accidents and near misses along the A505.
"The reason for the campaign in the first place was because we had so many people calling us in and talking about the number of crashes on the A505 and we thought it was about time to take a stand."
"This is a complex issue and there are a range of factors that need to be taken into consideration as part of the study. Unfortunately the chief cause of accidents on our county roads remains dangerous driving and we strongly urge all motorists to drive safely."
Lynsey is realistic about the prospect of a redesign of the road. It would be costly but she says it would save lives.
In the meantime she's calling for an immediate reduction in the speed limit to reduce the risk for motorists.
