Speed cameras on the new Bridgewater Bridge will start issuing fines from this Friday.
Authorities have confirmed the launch date after detecting an average of 800 speeding offences each week during the seven-week testing period.
From August 1, the cameras will enforce the bridge’s 80km/h speed limit, with motorists risking fines of up to $1,178.75 and six demerit points for each offence.
Transport officials say they are alarmed by the number of drivers caught speeding during testing, calling the figures “completely unacceptable”.

“During testing we have been concerned with the level of speeding on the bridge and ask all motorists to slow down and obey the 80km/h speed limit,” a State Growth spokesperson said.
“No level of speeding is safe but the number of offences being detected is completely unacceptable.”

Regular commuters are being warned that repeat offenders could rack up multiple fines, with authorities stressing that every detected incident will result in a separate infringement notice.
“If you frequently drive the new Bridgewater Bridge above the speed limit, you will be penalised each time you are detected speeding and could end up losing your licence,” the spokesperson said.
The new cameras are identical to those on the Tasman Bridge.
They can monitor traffic in all lanes and detect speeding vehicles travelling in both directions at the same time.
