220527 Sight Distance Assessment and IR Responses

Figure 4 – Available sight distance to the west from the proposed vehicle crossover




Figure 5 – Available sight distance to the east from the proposed vehicle crossover

Table 1 below details the: -
    • relevant design speed
    • minimum domestic driveway sight distance (from Figure 3.2 AS2890.1); and
    • current available sight distance (measured on site).


Table 1 – AS2890.1 required sight distance and available sight distance for the proposed
vehicle crossover
