New traffic lights are being installed at a busy intersection to remove confusion for drivers and make the road safer.
Work is underway on the upgrade of Kingston Road and MacArthur Crescent/Jean Street at Logan Central.
The $100,000 upgrade will increase safety for south-bound motorists on Kingston Road, according to Woodridge MP Cameron Dick, who said he undertook community consultation.
"Talking to our community, we discovered some drivers were seeing the next set of traffic lights at Paradise Road turn red and were confused with the right-turn arrow signals at Jean Street," Mr Dick said.
"We've heard about vehicles stopping in the middle of the MacArthur Crescent and Jean Street intersection, which is dangerous and causes congestion.
"The traffic signals will be installed on the south-bound side of MacArthur Crescent and will usually stay green, removing the confusion around the visibility of the traffic signals ahead at Paradise Road.
"And those turning right into Jean Street will see new six-aspect lights, allowing for a controlled right turn."
Waterford MP Shannon Fentiman said bike riders will also benefit from the upgrade, with new signs highlighting the option to travel along Kingston Road with the traffic or via the off-road path.
"We want to make sure Logan families and the community can get to where they need to safely," Ms Fentiman said.
"It's great to see there will also be improvements to on-road bike lanes to allow for safer road sharing.
''These changes will make things easier and safer for all road users - it's a sensible solution that will fix a confusing local traffic issue."
Safer Roads Sooner has provided the funding for the work, which will take four weeks.
Kingston road is one of Logan's busiest, with a string of accidents already this year.
A motorcyclist was killed earlier this month at Slacks Creek.
The 25-year-old motorcycle rider died when he hit another vehicle at the intersection with Wembley Road.
The motorcyclist was pronounced dead at the scene, and the accident closed Kingston Road in both directions.
Four cars were involved in a smash which shut the southbound lanes of the road in May.
One person was taken to hospital.
A crash further along Kingston Road in March had police appealing for witnesses.
The accident left a man trapped while three others fled the scene at Waterford West.
Three ambulance crews, including a critical care paramedic. went to Loganlea in March after a car rolled on Kingston Road, near Chambers Flat Road.
