Highways Act Orders and Schemes

5.20 A new PMA is shown by narrow diagonal hatching. New PMAs should be a fixed
width starting from the highway or carriageway boundary of the highway from which
access is being taken. Where there is a need to provide visibility at a junction by
setting back the fence line, the new access will be set back behind the revised
fence line. However, it may be more readily understood if the new PMA is shown to
the carriageway boundary. New PMAs should be numbered 1, 2 etc, working from
left to right across the site plan, with the number placed in a circle. Each site plan
will start again at 1, 2 etc.
5.21 The PMA should be shown till it enters the last landholding which it serves.
Beyond that, any work will be accommodation work at the landowner’s discretion.
Combining different keys
1. Where stopping up a highway or PMA coincides with a new or improved
highway or new PMA.
5.22 Normally, both the stopping up and the new or improved highway or new PMA will
be shown on the main site plan. However, this can be difficult to do with clarity.
Where a stopped up highway coincides with a new highway or PMA, ideally the
markings for the new highway or PMA will be placed between the zebra hatching
marking of the stopped up highway. If space does not allow clarity, show one set of
markings on the main site plan and the other set of markings on an inset. Similarly,
where an improved highway coincides with a stopped up PMA, the stopping up
can be shown through the improvement marking. But if this is unclear, or where the
stopping up of a PMA (a solid black line) prevents any other marking being seen,
the new or improved highway or new PMA would be better shown in an inset.
5.23 The aim (and challenge) for drafters is to show the information as clearly as
possible. For example, where quite long lengths of local highways and/or PMAs
are subject to stopping up, and are to be replaced with new and/or improved
highways and new PMAs, it may be more helpful to show one set of markings on
one big inset, and show the second set of markings on a similar sized second
inset if possible, placing both insets side by side on the same site plan sheet.
5.24 An alternative way to show stopping up is to show it only where no new or
improved highway or PMA are being provided at the same locations. Where new
or improved highway or PMA does coincide with stopping up, it is the improved/
new highway or PMA that is shown rather than the stopping up. In effect, they
are drawn over the stopping up so that the stopping up no longer shows. This
style can provide clarity on what is ultimately intended and can be a useful way
of presenting small and relatively simple schemes. But it does not show the full
picture and would not be appropriate for complex junctions and major schemes.
