Key issues
About 20 to 30 construction vehicles would be required to service this proposal each day. The Sydney City Centre Bus
Infrastructure and Sydney City Centre Cycleway projects will require the use of about 60 construction vehicles per day.
As such, there is potential for a cumulative increase in construction traffic on the city centre’s roads.
The above traffic would be introduced onto roads that currently carry several thousand vehicles per hour (refer to
section 6.1 and Chapter 2). As such, the addition of up to 90 vehicles per day would contribute less than 0.001 per cent
to the city’s existing traffic volumes. This would have a negligible impact on congestion, network performance or travel
delays to all road users, pedestrians and cyclists. The cumulative effect is therefore assessed as negligible.
Traffic management controls would be installed across the proposal footprint during construction (refer to section 3.3).
The duration, type and extent of controls would depend on the improvements being installed in any given location. It is
assumed that these controls could be in place for over three months in locations where more major work would be
taking place (refer to Table 3-3 to Table 3-7). The controls could be relaxed during high demand (ie peak) periods so as
not to affect the city’s road network performance (refer to section 6.1.3).
Traffic management controls would be implemented in the following locations that coincide with this proposal’s footprint:
NW2: King Street, R2: Market Street, S2: Goulburn Street and S6: Pitt Street (for the CSELR)
NW1: Kent Street and R4: Clarence Street (for the Wynyard Walk project)
NW2: King Street, R1: Park Street, R2: Market Street and C2: College Street (for the Sydney City Centre Cycleways
projects)
All work sites except NW2: King Street (for the Sydney City Centre Bus Infrastructure project).
Together these could lead to additional cumulative effects on congestion, network performance and travel delays, with
impacts on road users (including bus users), pedestrians and cyclists.
Safeguards and management measures to avoid and/or minimise the proposal’s traffic management are provided in
section 6.1.4. The construction staging and program would also be developed cognisant of the controls introduced under
the above projects, with specific areas of conflict identified in the construction traffic management plan (refer to
section 6.1.4). Conflict would be managed by:
