Appendix D - Sight Distance Assessment

  AS2890.1 – Sight Distance Requirements                    Sightlines achieved


  95m to the left (measured to the centre line)             Yes (Refer Photo 1)


  95m to the right (measured to the edge line)              Yes (Refer Photo 4 & 5)


As detailed above Tod Consulting is confident that compliant sight distances can be achieved in both
directions.
                                       Sightline to the Left

Visibility to the left is unimpeded for a distance exceeding 160m. There is sag in the road approximately
150m from the proposed (existing) access and a bend an additional 120m further on from the sag point.
The available sight distance exceeds the requirements of AS2890 for an 80kph speed limit and would
achieve the requirements for a 100kph speed which is reassuring as the geometry of the road in this
location is likely to result in prevailing speed of vehicles exceeding the 80 kph speed limit.

The photo below shows the visibility available from the access point looking left.
