The A68 in the Scottish Borders is closed in both directions due to an accident between A6088 (Carter Bar) and the A696/A68.
Two speed cameras on the A68 between Huntford and Camptown in the Scottish Borders were the target of vandals over the weekend.
Both cameras were destroyed with a saw, bringing the total number of speed cameras sabotaged with a saw to six.
Lothian and Borders Police are investigating the incident as it is theft, vandalism and attempting to pervert the course of justice.
Superintendent Denise Mulvaney from Lothian and Borders Police, said:
"There appears to be a systemic campaign of violence aimed at safety cameras.
"The method used to attack the cameras is highly dangerous, the people responsible for these actions are putting their own lives at risk as well as the safety of others.
"Anyone who comes into close contact with a camera that has been attacked in this fashion could be electrocuted.
"I'm urging any member of the public who has information they think might relate to any of the crimes aimed at safety cameras to contact the police."

"What these figures are showing is that there is a higher accident rate on those parts of the road that are not duelled or those parts that do not have a crawler lane.
"I think it is very important that the government does all it can to try and invest in the road so it is made as safe as possible to ensure these accident figures are reduced for future years."
Calls are being made for one of the main roads in the Borders to be upgraded.

"The A68 is used by Borders residents thousands of times a year, as it is one of the key routes for getting between the Borders and Edinburgh to the north and Newcastle to the south.
"It is therefore important that it is made as safe as possible for motorists to use, but these statistics show that there are too many accidents happening on it.
"Many people will be shocked that nearly 500 accidents have occurred on it in the last ten years, with 100 of them being serious and 15 fatal."
