The new Mandurah Bridge has opened to traffic for the first time with two of the four lanes in action.
Traffic is moving on the eastbound side of the bridge with one lane getting through in each direction.
The old Mandurah bridge is now permanently closed with demolition works to start in the next few days.
During the works the road on the old bridge will be retained as a working platform for cranes, trucks and other machinery to access the bridge from the west.
In shallower water on the eastern foreshore, bridge sections will be attached to flotation devices, separated from the bridge structure, then lifted out by a crane.
A spotter will ensure there are no marine mammals in the vicinity and a silt curtain will contain any debris.
The under-bridge fishing platforms and columns will be cut with a saw, then tied to inflatable airbags and floated to an area on the western foreshore for removal.
This work method will reduce the impact on the riverbed and marine environment.
A spotter will ensure there are no marine mammals in the vicinity and a silt curtain will contain any debris.
Works are not expected to significantly affect boats travelling on the estuary, with no closure of the waterway planned.
Boat traffic should approach the area slowly and follow all signs and signals in the area.
The majority of the materials removed from the bridge will be recycled, including road base, steel and concrete.
Timber salvaged from the bridge will be returned to the City of Mandurah.
Once the City knows how much timber is available they will ask the community to contribute thoughts on how it is to be distributed and utilised.
Mandurah Terrace also re-opened on Wednesday morning.
