The speed limit on five inner-Brisbane roads could be dropped to 40km/h to ensure the safety of 4000 Brisbane State High School students and parents crossing the major roads every day.

The behaviour of motorists on Cordelia Street, Vulture Street, Merivale Street, Gladstone Road and Ernest Street in South Brisbane is currently being assessed by Brisbane City Council.

The council’s infrastructure chairman Amanda Cooper said the council had progressively been installing school zones on busy multi-lane roads where pedestrian safety concerns existed.

The council will finalise its plans for the area in the coming months.
