Just out of interest, when you say 'length of roads', do you mean the<br>
length of all ways in that postcode, or only ways labelled as trunk,<br>
residential, etc, but excluding cycleways and paths? Also, do these<br>
figures include off-road tracks? You could find some of the<br>
'overmapped' areas, contain lots of off-road tracks.<br>
<br>
Very interesting figures though, and Id love to see if such figures<br>
could be generated for other parts of the country.<br>

Even more frequently, monthly for example would give a good indication<br>
of the progress as it happens.<br>
