There is no economic or environmental justification for upgrading the whole route to dual carriageway standard.
However, the road is designed to make possible upgrading to a dual carriageway if that is justified by the volume of traffic.
The northbound carriageway was mainly constructed with conventional hot-rolled asphalt.
It has an undivided carriageway of 2,300 yards, wellset-back residential property and further development in progress.
The width of the existing carriageway between verges is from 18 feet to 21 feet, and is only sufficient for two lines of traffic.
It may decide to narrow the carriageway and perhaps put green verges between the carriageway and the footpath.
I regret that no information is available concerning vehicle mileages on dual carriageways or different types of motorway.
Now, the vast majority of the road is either motorway or dual carriageway, and my journey time has been halved.
