College. Pedestrians, including students, use these structures when crossing Maple St and
to access nearby bus stops.

3.2.2 Crystal St limitations include a blind curve, many vehicles parked kerbside and a
busy intersection at Myall St opposite the Cooroy Golf Course.

3.2.3 Old Ceylon Rd has a 6.2m sealed road width and insufficient vertical clearance
between the unsealed shoulders and overhead trees. State road guidelines recommend a
35m lane width for MCV use of two lane sealed roads.

The Old Ceylon Rd/Cooroy-BeIIi Creek Rd intersection has a degraded surface, poor
sightlines and a Give Way sign. Given the 80kph speed limit on the Belli Creek Rd and the
sweep path of a heavy vehicle, trucks turning left into and right out of Old Ceylon Rd
increase the potential for accidents and the obstruction of other vehicles.

3.2.4 The Cooroy-BeIli Creek Rd beyond No. 129 is part of an established cyclist training
and event route with a minimum sealed road width, narrow shoulders, poor sightlines,
unmarked concealed entrances and an 80kph speed limit. The interaction of heavy trucks
with cyclists raises road safety concerns given the 2014 bicyclist road rules, which require
a 15m clearance when overtaking cyclists on 60+kph roads, while permitting drivers to
cross unbroken centre lines, and cyclists to ride two abreast.

4.0 Proposed mitigation works - Top Forestry Rd
The proposed minor mitigation works are inadequate and inappropriate. They do not
effectively address Top Forestry Rd's limitations to carry increased volumes of heavy
vehicle traffic. The works would increase road maintenance frequency and costs. The
proposed works, signage and vegetation removal would compromise the road's visual
amenity. Vegetation clearance also would destabilise road edges and increase the dust
spread range.
The works are based on an ARRB suggested minimum carriageway width of 55m. The
Qld DTMR classifies a 19m/50T B-Double as a Multi-Combination Vehicle. MCV route
guidelines recommend a minimum 8m width for unsealed roads (pI4). The standard
width of a prime mover is 2.9m (25m cab + 200mm each side for wing mirrors). The
combined width of two on-coming B-Doubles/ AVs would be 5.8m with no clearance
between vehicles. A minimum 55m road width does not address the safety risks
associated with the passage of on-coming heavy trucks, especially as the road shoulders
are unstable or non-existent. Nor does it mitigate the risks for other drivers.

4.1 Section 1 No mitigation works are proposed, however the narrowest part just before
King Parrot Lane is edged by large trees and a steep bank that has subsided twice in the
last 4 years.

4.2 Section 2 Widening parts of Section 2 would require the removal of large, mature
native trees on both sides of the road and the stabilisation of road edges and a subsiding
bank. L&R states that the 670m-long Section 2 has road widths of 5.0m - 5Am, but
recommends that only a 350m length be widened to 55m.

4.3 Section 3 The installation of a 45m wide, 236m-long, one-way system in Section 3 for
the benefit of the poultry operation would inconvenience other road users and impede
normal traffic flow. This system raises safety concerns given the road's long-term,
customary 2 lane use.

The alternative road widening proposal at chainage 1100m "involves significant slope and
