SUMMARY
Detailed
design plans have been prepared for a contra-flow bicycle facility between
Dobroyd Parade and Hawthorne Parade, Haberfield. Consultation with affected
residents and owners was undertaken on the draft detailed design plans in
February and March 2020. It is recommended that the detail design plans are
approved for construction.
RECOMMENDATION
THAT:
1. The proposed diversion plan
for pedestrian and cyclists for future works along the Bay Run be noted; and
2. The plan (Attachment 1) for
a contra-flow cycle facility in the one-way link road between Dobroyd Parade
and Hawthorne Parade, Haberfield be approved for construction and be
implemented in advance of the Bay Run works.

BACKGROUND
In August
2018 Council adopted the Cooks to Cove Greenway Master Plan. Based on the
adopted Master Plan concept designs were developed and endorsed by Council in
May 2019. Council is now developing detailed design plans to facilitate
construction.
As part of
the works it is proposed to upgrade the Bay Run east of UTS rowers to Lilyfield
Road, including the Lilyfield Road bridge. To facilitate upgrade and widening
of the shared path through this section the seawall will be required to be
widened into Iron Cove.

Whilst
pedestrian and cyclist access will be maintained as much as possible, for
periods of the construction it will be necessary to divert all pedestrians and
cyclists. This would include, at a minimum; during construction of parts of the
seawall, construction of a widened ramp up to Lilyfield Road Bridge and
construction of a ramped connection to the Greenway.
There is no
room for pedestrians and cyclists to travel adjacent to the proposed works area
due to the proximity of the City West Link. As such a diversion route is
required.
Proposed pedestrian
and cyclist diversion plan.
During the
works it is proposed that cyclists and pedestrians would be diverted from the
Bay Run at Timbrell Drive across the City West Link and up Mortley Avenue.
Access to the
UTS rowers would be retained from the café and along the existing path
west of the club and from the carpark.
From Timbrell
Drive, pedestrians would be diverted through Robson Park, along part existing
and part new path, and then along an existing path through the park lands
adjacent to the City West Link. From here pedestrians would travel along
Dobroyd Parade, Hawthorne Parade, and Canal Road to re-join the Bay Run at
Maliyawul Street. The total length of the diversion would be 1.6km. This
compares to the regular route of 1.0km.
The path
through Robson park is only 2.1m wide and would not be suitable for the high
numbers of cyclists using the Bay Run. Instead cyclists would be diverted on-road
up Mortley Avenue, down Boomerang Street and along Crescent Street. From here
cyclists would travel along Dobroyd Parade, Hawthorne Parade, and Canal Road to
re-join the Bay Run at Maliyawul Street.

The low
traffic numbers are generally suitable for an on-road route although it is
noted that less confident riders may ride through Robson Park and along the
shared path following the same route as pedestrians.
Based on
historic traffic counts, traffic numbers along the proposed diversion route are
as follows:
· Mortley Avenue:
5500 to 6000 AADT
· Boomerang Street
(north of Mortley Avenue): 1200 to 2000 AADT
· Crescent Street:
500 to 600 AADT
· Tillock Street:
500 to 600 AADT
· Hawthorne Parade
to Dobroyd Parade one-way link: 255 AADT
All roads
except Mortley Avenue have low traffic volumes suitable for an on-road cycle
route. Mortley Avenue forms part of an existing cycle route, but existing
conditions are suboptimal due to the mixed traffic and high traffic volumes
combined with a significant incline.
Further
investigation and designs to facilitate the diversion route will be undertaken
as part of the Bay Run upgrade detailed design. This is likely to entail
investigation of:
· Improvements to
the intersection of City West Link, Timbrell Drive and Mortley Ave
· Marked up-hill
shoulder lane and mixed traffic down-hill lane on Mortley Ave
· Extension of
Robson Park path network and conversion of the path through Robson Park to a
shared path
· Crossing point at
Boomerang Street
· Conversion
of the path link from Boomerang Street to Dobroyd Parade to a shared path
· Conversion of the
Dobroyd Parade to Hawthorne Parade one-way link to a contraflow
The
conversion of the Dobroyd Parade to Hawthorne Parade one-way link to a
contraflow bicycle facility is discussed in detail below.

In accordance
with RMS Technical Direction td14-02 a contra-flow bicycle facility may take
the form of a marked lane or as a movement designated by signs only. Both
facilities require combinations of regulatory and supplementary signage.
Pavement markings that raise awareness of bi-directional bicycle movements are
also recommended.
The one-way
road width is 4.2m wide at its narrowest point and widens at either end to over
6.0m.
A 1.4m wide
marked contra-flow bike lane could be implemented along the length of the
one-way section on the northern side; however, given the short distance (55m),
very low traffic volumes (255 AADT), adequate sight distance (30m) and low
speeds (35km/h 85%ile speed) it is considered movement designated by signs and
pavement markings only is appropriate.
The proposed signage and pavement marking changes are shown
in the detailed design plan in Attachment 2. This includes signage
changes at either end of the contra flow facility as well as a bicycle pavement
markings.
Associated
with this is modification to existing parking signage and line marking in
Hawthorne Parade just south of the proposed contra flow facility to enable
cyclists to transition from on-road to the Greenway path safely, whilst also
facilitating turn movements for vehicles. The proposed changes would result in
the loss of three car parking spaces.
Modifications
to the one-way link between Dobroyd and Haberfield Parade and parking in
Hawthorne Parade are proposed to be implemented as part of the Richard Murden
Reserve park upgrade. These works are anticipated to be undertaken in mid-2020.
It is
intended that the changes are retained on a permanent basis to facilitate shut
down of the Bay Run should it be required in future and provide a better
connected bicycle network.

PUBLIC CONSULTATION
A notification letter and plan of
the proposed works was delivered to residents of properties within 100m of the
one-way link on Dobroyd and Hawthorne Parades on 17 Feb 2020. A total of 16
letters were distributed. Inner West Bike Coalition was also contacted for
comment.
One response was received from
Inner West Bike Coalition in support of the proposed works.
