Martin:
Where is this “A” road with 3 continuous lanes?Don’t say the A14 as that only becomes 3 lanes due to lane 1 being briefly being an on/off slip…
Actually I think we can say A14, as there is now a three mile section (J7-J9) around Kettering which is 3 lanes in each direction, plus the 6.5 mile section past Newmarket between the two A11 junctions already mentioned.
