PROPOSAL Iluka Resources
is seeking endorsement from the Shire of Dandaragan of the designs of the
Mimegarra Road / “Mine Access Road” intersection, “Haul Road Crossing” and Mimegarra
Road / Brand Highway intersection to enable them to proceed to construction
phase.
BACKGROUND
Iluka Resources has had ongoing consultation with Shire staff regarding various
components of their Cataby Project. A key component of this that affects Shire
assets and infrastructure is proposed design and construction of the following
intersections along Mimegarra Road
- Mimegarra Road / “Mine Access Road” intersection
- “Haul Road Crossing” and
- Mimegarra Road / Brand Highway intersection
The design of these intersections was previously put to
Council for approval at the September 2014 Council Meeting. At that point in
time Shire officers indicated that there were a number of issues that required
further discussion and resolving between the Shire, Iluka and Main Roads WA.
These primarily related to the following:
- Specific technical design issue regarding the inclusion of a northbound left turn pocket from Brand Highway into Mimegarra Road.
- Specific technical design issue regarding the inclusion of a westbound right turn pocket from Mimegarra Road into the “Mine Access Road”.
- Specific technical design issue regarding the inclusion of an eastbound acceleration lane from “Mine Access Road” turning into Mimegarra Road.
- Battery Limits and Cost Contribution for Mimegarra Works.
- Timing of Iluka’s Mimegarra and Brand Highway works in relation to the Shire’s proposed upgrade of Mimegarra Road.
The following resolution was moved: Moved Cr Bailey,
seconded Cr Short
That Council:
1. Endorses IlukaResources’ concept design of the Mimegarra Road / “Mine Access Road”
intersection and “Haul Road Crossing” to proceed to detailed design stage.
2. Request the
CEO to have follow-up discussions with Main Roads WA regarding the following
design issues:
- The inclusion of a left turn slip lane with an acceleration lane from “Mine Access Road” into Mimegarra Road.
- The inclusion of a westbound right turn pocket from Mimegarra Road into the “Mine Access Road”.
- The inclusion of a northbound left turn pocket from Brand Highway into Mimegarra Road.
3. Delineate
Iluka Resources’ “battery limits” for their works to be undertaken on Mimegarra
Road to be from SLK 0 (Brand Highway intersection) through to SLK 1.500 inclusive.
Iluka Resources will be responsible for the cost and construction for all works
within this area from Brand Highway intersection to SLK 1.500 including:
- Mimegarra Road / Brand Highway intersection;
- “Mine Access Road” (Mimegarra Road);
- “Haul Road Crossing” (Mimegarra Road);
- Services Crossing Mimegarra Road; and
- Mimegarra Road pavement and seal from SLK 0 to SLK 1.500.
4. Request the
CEO to negotiate an ongoing maintenance agreement, with Iluka, for Mimegarra
Road between SLK 0 and SLK 1.500.
5. Request the
CEO to have follow-up discussions with Iluka Resources regarding the timeframe
and scheduling of their Mimegarra Road and Brand Highway works in relation to
the Shire’s proposed scheduling of works for Mimegarra Road upgrade.

COMMENT
Since the September 2014 Council Meeting further discussions have taken place
between Shire officers, Main Roads WA and Iluka Resources.
The key design issues raised by Council at the September
2014 Meeting Shire were put to Main Roads WA for comment and ultimate
endorsement of the design. The following provides a summary of Main Roads
response as received via email (Doc Id 86466).
“The drawings provided by Iluka have been reviewed by Main
Roads and the following comments are provided for consideration in finalising
the design:
BRAND HWY LEFT
TURNING LANE A left turn lane is required to accommodate northbound
vehicles turning left into Mimegarra Road. This section of Brand Hwy has
limited overtaking opportunities south of this area and the site has a single
barrier line which will stop following vehicles overtaking the turning
vehicles.
LINE MARKING &
SIGNAGE Iluka to review and update drawings of the submitted Signs and
Pavement marking drawings to reflect the comments from Main Roads as outlined
below in conjunction with the relevant Main Roads’ guidelines drawings:
- All existing and proposed signage should be detailed by a precise longitudinal location by an appropriate chainage / dimension or SLK from a known point;
- All pavement marking lengths and precise location should be indicated by an appropriate chainage, dimension or SLK showing how to tie-in to the existing pavement marking;
- Free flow slip lane island - edge line to be 300mm offset from kerb (refer attachment)
- Free flow slip lane island for traffic exiting Mimegarra Road not delineated and travel path is not defined. Line marking on approach to median island to be revised – Include edge line/RRPM’s on the approach and tie into edge line of the through alignment;
- Mimegarra intersection apron not clear in relation to the travel path. Recommend some form of treatment is applied to define the edge of seal and outer travel path.
- Scale bar to added in drawings;
- Lane widths to be detailed;
- Recommend RRPM’s be installed through overtaking lanes as per MRWA drawing 200631-0039-10;
- MRWA follows the Australian Standard 1742.2 for the installation of “STOP” signs with warrants based on visibility alone. Based on the available sight lines at the intersection the installation Give Way sign control is considered appropriate;
- Does the proposed upgrade include the upgrade and sealing of Yandin Rd intersection? Only 10m of pavement marking is proposed - Recommended - 25 metres double two way barrier line;
- Recommend consideration be given for the installation of guideposts/red unidirectional RRPM’s at the overtaking lane merge tapers in accordance with MRWA drawing 200631- 0039-10.”
Based upon this information received, Shire officers are now
happy with design proposed by Iluka resources subject to above mentioned
requirements outlined by Main Roads.
Shire officers still maintain that the following continue to
be pursued with regard to the Shire’s ongoing position with Iluka regarding
battery limits and maintenance:
1) Delineate Iluka Resources’ “battery limits” for
their works to be undertaken on Mimegarra Road to be from SLK 0 (Brand Highway
intersection) through to SLK 1.500 inclusive. Iluka Resources will be
responsible for the cost and construction for all works within this area from
Brand Highway intersection to SLK 1.500 including:
§
Mimegarra Road / Brand Highway intersection;
§
“Mine Access Road” (Mimegarra Road);
§
“Haul Road Crossing” (Mimegarra Road);
§
Services Crossing Mimegarra Road; and
§
Mimegarra Road pavement and seal from SLK 0 to
SLK 1.500.
2) Request the CEO to negotiate an ongoing

1.500.
