2016-02-02 I&S Committee - Item 4 - Attachment 1 - Noosa Traffic Study

Eumundi Noosa Rd route. In the longer term (assuming Beckmans Road is duplicated by
DTMR), the capacity of the Eumundi Noosa Road route is likely to be constrained by the Rene
St / Gateway Dr intersection, for which there are no obvious options for upgrading. Thus, it will
be necessary to either maximise the traffic capacity of the Poinciana Ave – Doonella St -
Memorial Ave – Hilton Tce route within the existing framework (which is recommended in this
report), or require planning for conversion of Eumundi Noosa Road intersections to full traffic
signal control (which is not recommended and which would be contrary to Noosa’s road
planning philosophy).

It is noted that the daily traffic flows depicted in Figure 12 indicate 24,000 vehicles per day on
the Memorial Ave bridge (also known as Doonella Bridge), which is greater than the normal two
lane road traffic flow limit. However, 2-lane bridges often carry in excess of 20,000 vehicles per
day provided the intersections at each end have sufficient capacity. For example, the two-lane
Walter Taylor Bridge at Indooroopilly in Brisbane carries 32,000 vehicles per day.
Recommended upgradings of the Ernest St / Hilton Tce intersection and the Doonella St /
Memorial Ave intersection (as discussed later in this report) at each end of the bridge would
enable the estimated 24,000 vehicles per day on the bridge to be achieved.
