Users of the A12 will know that the road is already a dual carriageway for the length studied in the inquiry (from the M25 to the A14). What the inquiry recommends is that the standard of provision should be brought up to date and made consistent.
At present, lane widths vary from section to section, as do the marginal strips, and there
are occasional sections of three-lane dual carriageway.
The three-lane provision is seemingly ad hoc and not related to the volume of traffic. Lay-by provision, street lighting and accesses have also been highlighted as deficiencies.
Your article goes on to state that the road runs from east London to Felixstowe. This is not so: it runs from London to Great Yarmouth. Felixstowe and Harwich are mentioned in the inquiry report because much of the traffic from the ports uses the A12, and both ports have plans for significant expansion.
The report (but not your article) makes two particularly interesting recommendations. Firstly, a speed limit of 60mph should be introduced between Hatfield Peverel and Marks Tey. Secondly, that over the same length of the A12, there should be an overtaking ban for HGVs.
As a daily user of the A12, I await these developments with great interest.
