Engineers to assess flood-damaged bridges on key WA route amid concerns some could take years to fix

Engineers will assess the destruction of major bridges on the trucking route connecting Western Australia and the Northern Territory on Wednesday amid concerns key infrastructure could could take months, or even years, to fix.

Main Roads WA and structural engineers will assess the Fitzroy River Bridge on the Great Northern Highway, as photos and videos emerge showing that the bridge has collapsed after being hit with record floods.

Water is receding at Fitzroy Crossing, but Guardian Australia understands there are concerns it could take months or years to fix the bridge.

Main Roads WA has suggested building a temporary bridge while the official one is rebuilt.
