John Lamont, MSP, is calling on the Scottish Government to make the A68 safer.
Statistics revealed there have been nearly 500 accidents on the road in the past 10 years between the Scottish border and Edinburgh.
Mr Lamont is now calling on the Scottish Government to make the road safer after 15 people died on the stretch.
"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."
"It is a clear indication that more needs to be done to improve safety on the road, and the onus is on the Scottish Government to take action to cut down the number of collisions."
