This section of road has a daily flow of 23500 vehicles which is over capacity for a road of its type. Currently the road does a very poor job as both a major trunk road and a local access road. A new dual carriageway road will leave the old road to be used as a high quality local access road for buses, cyclists and local traffic. It will improve safety and resolve the toxic air quality issues at Tideford.
