We did

The EPA decided not to assess the proposal and did not provide formal advice.


The EPA has received a referral of a proposal from the proponent, Main Roads Western Australia, to replace the existing Mandurah Traffic Bridge which spans the Mandurah Channel at the northern end of the Peel Harvey Estuary System. The existing timber bridge has reached the end of its functional life and would be demolished once the proposed new bridge was close to completion. The proposed new bridge would be situated to the north of the existing bridge and be constructed of concrete.

It is anticipated that construction of the new bridge would require minimal seabed disturbance in the form of pile-driving the foundations and no dredging of the Mandurah Channel is proposed. The extent of proposed disturbance is 7 ha, of which 0.2 ha is native vegetation.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The Chairman's decisions on level of assessment are released each Monday on the EPA's website.
