5.6.3          Intersection 3: Eumundi Road/Walter Hay Drive/Venture Drive
The intersection of Eumundi-Noosa Road/Walter Hay Drive/Venture Drive is currently a four-way roundabout
with varying circulating lane widths, under the authority of the Noosa Council. The intersection provides
access to Tewantin to the north-west of the intersection and Noosaville to the north-east. The intersection
also functions as the sole access to the industrial estate located immediately west of the intersection. The
most recent aerial imagery of the intersection is shown alongside the analysed intersection form on Figure 5-
6. Results for the analysis are summarised in Table 5-8.
