Environmental surveys in Swan River from 7 December

From 7 December, Main Roads WA will be undertaking environmental surveys and investigations in the Swan River near Fremantle.

Divers and support vessels will be in the water upstream and downstream of the Fremantle Rail and Traffic Bridges and the Stirling Bridge.
