It is the right turn out of Symes Road that is of particular concern. Most drivers won't even attempt this turn. However, there are some who are willing to take the risk. From observations, in most instances the turn cannot be completed in one go. This is an extremely high risk manoeuvre in this environment and will often result in some form of evasive action by other traffic, ie sharp braking or sudden lane change.
Visibility is limited due to the location of the intersection with respect to the overbridge.
It is only possible to see a vehicle approaching when it appears over the top of the bridge. These vehicles are often travelling at speeds in excess of 60 kph. The turning traffic volumes were surveyed over three separate one hour periods, these being morning peak, off peak and evening peak. Around one third of these are heavy vehicles. It is considered that this is directly associated with the complexity and high risk in this manoeuvre.
