UPCOMING WORKS:
NORTHERN ZONE
Leach Hwy and Tonkin Hwy, Cloverdale and Redcliffe
Continuing throughout January and February 2015
Passing members of the travelling public can now see the
final alignment of Tonkin Highway taking shape in the
vicinity of Leach Highway. The alignment is adjacent to
the stretch of road currently in use and travels under the
largest bridge of the new interchange and over the top of
another bridge and pedestrian / cyclist underpass. The
asphalt placement has progressed well during the start of
summer, along with some of the finishing works such as
kerbing, street lighting and both concrete and steel
permanent safety barriers. Whilst asphalting for the
Tonkin Highway alignment continues underneath the
main bridge and at the intersection of Dunreath Drive, the
team is also focusing on preparing the area on top of this
bridge, which will take traffic travelling from Leach
Highway to Airport Drive, as well as the on-ramp for the
Tonkin Highway southbound carriageway, for asphalting.
The realignment of a section of Tonkin Highway
northbound traffic between Great Eastern Highway and
the Dunreath Drive intersection toward the east late last
year has opened up a significant work area allowing the
construction of the new Tonkin Highway / Dunreath Drive
interchange and upgrade of the highway to also progress.
In late December the bridge deck was poured and in
early January the final Mechanically Stabilised Earthwalls
(MSE) panels were installed for the new interchange
structure. Looking ahead, earthworks and pavement
construction activities will continue to be the focus in the
coming months to build the ultimate northbound lanes of
Tonkin Highway between Great Eastern Highway and
Dunreath Drive intersection and the new interchange
structure adjacent to Redcliffe Park.
Upcoming work details
LEACH HIGHWAY BETWEEN FISHER STREET
AND TONKIN HIGHWAY
TONKIN HIGHWAY BETWEEN FAWCETT
CRESCENT AND TERELINCK CRESCENT
Works to be undertaken in the vicinity of these areas
during this period include:
> Construction of road pavement, involving delivery,
placement and compaction of sub-base material and
laying asphalt
> Delivery and movement of construction materials and
earthworks to import and remove fill material around the
structures forming the new Tonkin Highway / Leach
Highway interchange, nearby the current intersection
> Traffic changes including the temporary closure of the
intersection of Dunreath Drive / Tonkin Highway
> Steel fixing, concrete pours and delivery of materials
for the construction of interchange structures.
TONKIN HIGHWAY BETWEEN TERELINCK
CRESCENT AND GREAT EASTERN HIGHWAY
Works to be undertaken in the vicinity of these areas
during this period include:
> Delivery and movement of construction materials and
earthworks to import and remove fill material, particularly
along the western side of the highway. This will include
the placement of approximately 50,000m3 of material in
the area adjacent to Redcliffe Park to backfill behind the
new bridge structure
> Steel fixing, concrete pours and delivery and lifting of
precast parapets and other materials for the construction
Reference: GWA-NZ-COR-0131
of new interchange structure
> Installation of road network drainage, involving
trenching and laying pipes, along the western side of the
highway between Great Eastern Highway and the existing
Dunreath Drive intersection
> Continuing to construct the Principal Shared Path,
involving asphalting, along the western side of the
highway, north of the Dunreath Drive intersection
> Road pavement construction, involving delivery,
placement and compaction of sub-base material and
laying asphalt, with a focus on the western side of the
highway between just north of Great Eastern Highway and
the existing Dunreath Drive intersection to construct the
ultimate northbound lanes of the highway
> Installation of a duoceptor, involving dewatering, sheet
piling and excavation, within the road reserve between the
Tonkin Highway southbound off-ramp to Great Eastern
Highway and Locock Street in Ascot. The duoceptor
separates oil from Tonkin Highway storm water runoff prior
to discharging into the river.
ACROSS THE NORTHERN ZONE
> Investigative activities including service location /
potholing and survey
> Adjustment of traffic barriers, changes to signage and
line marking and realignment of traffic to create safe work
areas and complete newly constructed areas
> Installation of services, including road network
drainage, street lighting and telecommunications
> Finishing works, including signage and steel and
concrete installation, and kerbing
> Landscaping activities, including the delivery and
spreading of mulch.
Changed traffic conditions
Changed traffic conditions will be in place while some of
these works are underway, including a reduced speed
limit and lane closures. Signage will be in place to guide
motorists through any changed traffic conditions. Motorists
are encouraged to factor additional time into their journey.
Working hours
Work in the Northern Zone will be carried out Monday to
Saturday day shift (between 7am and 7pm) and
Monday to Friday night shift (between 7pm and 5am),
excluding public holidays. There may also be occasional
weekend work required outside of these hours. Emergency
maintenance and repair work may also need to take place
outside of these times.
Gateway WA recognises the impact out of hours works
may have on local residents and will make every effort to
minimise disruption.
