<p>What you've said is correct for off ramps but would be incorrect
for on ramps.</p>
<p>The on ramp speed limit may be determined from the adjoining
road(s), as the last speed limit sign is the applicable limit
until you pass another sign.</p>
<p>So in the example given if the 60 sign was not on the link the
applicable limit would be what it was for Warwick Road, which from
memory is 70 near that underpass, and this would be the limit up
to the 60 sign.</p>
<p>So for this link it should be 70 - 60 - 100 as you go past the 60
and 100 signs.<br>
</p>
<p>Cheers</p>
