With respect to the houses on the north side of Reid Highway between Erindale Road and the Mitchell Freeway in Balcatta, I ask:
(a) what length and height of wall has Main Roads Western Australia built, or contributed to the cost of, in order to ameliorate road noise or block direct vision from Reid Highway, and when was this done and what was the cost;
(b) have any noise readings been undertaken to assess the levels of road noise impacting on these homes from this section of Reid Highway, and if yes, then when was this done, and will the Minister table a copy of any such noise report;
(c) are there any plans or preliminary designs to construct a wall or barrier to reduce the noise impact on these homes and provide greater privacy for residents, and if yes, will the Minister table a copy of such plans or designs; and
(d) what are the anticipated costs of any such works?

Main Roads West Australia advises:
(a) There is a 440 metre section of wall west of Erindale Road on the north side which is 2.1 metres high. A cost for this wall's construction is not available as the construction contractor's cost breakdown only ever provides a record of the total cost for building all the noise walls required for a project, not a specific location.
(b) A pre and post noise measurement for this area was undertaken.
(c)  Noise amelioration will be considered in the future at the time of the dualling of this section of Reid Highway.
(d)  Not applicable.
