Average speed cameras could be installed across a blackspot stretch of road linking Honiton and East Devon to Dorset.
Subject to funding, Highways England has confirmed a number of options to improve safety that could be actioned within three years.
Road safety campaigners have called for improvements to the A35, linking Honiton, in East Devon, to Charmouth, in Dorset. In the last year there have been four fatal accidents on the 13-mile stretch of road.
Kat Liddington, South West programme development manager for Highways England, said: “We are absolutely committed to improving safety on the A35 and we are currently working on a number of studies, including options around average speed cameras between Honiton and Charmouth and crossing points in the villages of Wilmington and Kilmington.
“These studies are still very much in development, but subject to funding we are hoping to implement the safety improvements within the next three years. In the meantime, we continue to work closely with Devon County Council and our police partners and we are keeping them, the parish councils and other interested parties informed as to progress.
“As part of this work, we are also undertaking a number of joint road safety campaigns aimed at influencing driver behaviour.”
Councillor Martin Shaw, Devon County councillor representing the Wilmington area, said: “The draft results of the study commissioned into the average speed camera option have shown that the proposed camera scheme across the 13-mile stretch of the A35 from Honiton to Charmouth, which also includes two crossings in Wilmington and one in Kilmington, could have real safety benefits.”
