T.P.D.M.V.23<br />

(Al/2001)<br />

3.3.8.8 At crests, where climbing lanes are provided both sides of the hill and there is less than<br />

500m between the ends of the tapers, the climbing lanes should be extended to overlap each<br />

other, providing a four lane carriageway at least 50m long. Continuous double white lines,<br />

if not used to separate the opposing lanes on either side of the hill, must be provided across<br />

the crest and extend at least 50m beyond the completion/start of the tapers in either<br />

direction, as in Diagram 3.3.8.4.<br />

3.3.8.9 Where the climbing lane exceeds 3 km in length it is advisable to provide some sections<br />

with a straight or large radius right hand curvature as an overtaking section of downhill<br />

traffic.
