The intersection of Marion and Sturt roads has replaced it as the most dangerous in the state.

The junction in Adelaide’s south has seen 40 crashes causing people to suffer serious or minor injuries in the past five years.

The next worst was the intersection of Curtis and Peachy roads in the northern suburb of Munno Para, which recorded 38 casualty crashes between 2017 and 2021 according to state government data obtained by the RAA.

The Britannia roundabouts finished equal third with 36 casualty crashes, along with the intersection of Stebonheath and Womma roads in the northern suburbs.

The dual Britannia roundabouts only recorded three casualty crashes last year – knocking the massively remodelled thoroughfare from top of the previous most dangerous intersections list during 2016-20.

Adelaide’s northern suburbs has more than its fair share of dangerous intersections, accounting for seven of the top 10 worst for casualty crashes, while the eastern suburbs has two and the south one.

The most common types of crashes at the 10 worst intersections were rear end collisions (38%), followed by right turn collisions (30%) and right angle (T-bone) collisions at 25%.

RAA Senior manager of Safety and Infrastructure Charles Mountain said thankfully none of the crashes at the 10 worst intersections resulted in a fatality in the past five years.

“Many serious injuries were recorded, which can have catastrophic and life-long impact on victims, their families and friends,’’ Mountain said.

“We can see that traffic volumes and the complexity of intersections contributed to the number of casualty crashes occurring at these top ten sites.

Mountain said the RAA is urging motorists to be vigilant whenever they are behind the wheel, particularly when travelling through these intersections – even if they do so every day.

“Traffic can stop abruptly and result in rear end collisions, so RAA is reminding drivers to keep a safe distance from the vehicle in front of them to avoid becoming a crash victim.’’

He said the majority of collisions resulting in injury at the worst intersection of Marion and Sturt roads involved vehicles travelling north and south.

“The Marion Road approaches to the intersection account for 80 per cent of casualty crashes, with right turn crashes very prominent for both north and south bound traffic,’’ Mountain said.

“Infrastructure improvements worth $3 million were last made at this intersection in 2015-16 and included road widening and a right-hand lane turn extension.’’
