Q: When will work start on this project?

A: Main Roads expects to award a contract in mid-

2020. Detailed design will then commence to allow

construction to start in October 2020.

Q: I have already provided feedback to this project

through the My Say Transport website, or other

means. Will I get further opportunities to provide

feedback during the detailed design process?

A: Yes. Main Roads and its successful contractor will be

engaging with local government, stakeholders,

residents and businesses as it progresses the detailed

design. Opportunities to participate in consultation

activities will be advertised to our project subscribers. If

you haven’t already subscribed, you can do this at

http://webcd.mainroads.wa.gov.au/cn/azvoz/projects.

Q: On which side will the new bridge over the Swan

River be built?

A: As part of its tender process, Main Roads has asked

contractors to price options to build new bridges on

both sides of the existing Redcliffe Bridge. This would

cater for the ultimate Tonkin Highway configuration

over the Swan River. If both bridges can be built as part

of this project, subject to budget considerations, it will

future-proof the new infrastructure for many years to

come.

Q: Will you be building noise and amenity walls as

part of this project?

A: Yes, we expect noise or amenity walls to be built

adjacent to most residential areas. The design and

location of these will be finalised as part of the detailed

design process, from mid-2020.

Frequently Asked Questions

Tonkin Gap Project and Associated Works

MAY 2020

Where noise or amenity walls are to be constructed on

property boundaries, the contractor will engage with

individual property owners. Read our Noise and

Amenity Wall Fact Sheet.

Q: Will trees in the highway reserve be affected by

the Tonkin Gap Project.

A: This is a very constrained site and there is no way we

can build the required infrastructure without clearing

vegetation. However, Main Roads is committed to

minimising the extent of clearing and is exploring

opportunities for local and regional environmental

offsets. Any clearing will also be undertaken with

appropriate State and Federal government approvals.

Q: I live alongside the highway or an entry/exit

ramp. How much closer will the road be to my

house?

A: Exact location details will be known once detailed

design is completed. We will make every effort to

minimise impacts to adjacent properties. This includes

exploring innovative engineering and construction

methodologies.

Q: What is the impact of the Tonkin Gap project on

Selby Park, in the City of Belmont?

A: An area of Selby Park has always been reserved for a

Tonkin Highway upgrade under the State

Government’s Metropolitan Region Scheme (MRS) and

this will be required to build the new loop ramp from

Great Eastern Highway. We are working closely with

the City of Belmont to minimise the impact and

determine how best to reinstate the park at the

conclusion of the works.

Q: Will Main Roads consider enhancing the

foreshore as part of the Tonkin Gap Project?

A: Main Roads has identified an area under the

Redcliffe Bridge, on the City of Bayswater side, that

may present an opportunity for enhancement. We are

already liaising with the City of Bayswater and other

State Government agencies to consider opportunities

in this location. Suggestions from stakeholders and the

community have so far included a skate park, fishing

platforms and shared path facilities. Further

consultation with local government, stakeholders and

the community will occur around these opportunities

after the contractor is appointed in mid-2020.

Q: What facilities are planned for cyclists and

pedestrians as part of this project?

A: The concept design includes a continuous Principal

Shared Path (PSP) along Tonkin Highway. This will

connect to the paths completed as part of the Gateway

WA and NorthLink WA project, as well as connections

to the local path and road network. These local

connections will be finalised during the detailed design

process, in consultation with local government,

Department of Transport and other stakeholder

groups.

Q: This section of Tonkin Highway, between Collier

Road and Dunreath Drive, is a bottleneck for road

users. Why did Main Roads not upgrade this section

as part of the Gateway WA or NorthLink WA

projects?

A: Main Roads continually plans ahead for new roads

and road upgrades, however construction is subject to

funding from the State and Federal Governments.

Funding for the Tonkin Gap Project was announced in

May 2019 as part of the 2019-20 budget. It includes

$232 from the Federal Government and $58 million

from the State Government.
