MAIN Roads WA (MRWA) is continuing to monitor the traffic safety on Great Eastern Highway following a reduction in the speed limit near the Scott Street intersection and says there are no plans yet for further reductions.

An MRWA spokesperson said after reviewing the speed environment along Great Eastern Highway near the Scott Street intersection, MRWA determined that 70kmh was the appropriate speed limit for that section of the highway.

“As a result, the existing 70kmh speed zone was extended approximately 3km east of Scott Street,” they said.

“For westbound traffic, the transition from 80kmh to 70kmh now occurs at Lionel Street.

“Main Roads committed to reviewing the effectiveness of the changes 12 months after implementation and this formal review has commenced, and is expected to be completed by September 2026.”

The spokesperson said traffic speeds and other relevant safety and operational information would be assessed to determine whether the changes were working as intended.

Greenmount resident and former head of East Metropolitan Health Service Colin Hughes said anecdotally there had been an improvement with the rate of accidents.

“We are down to one a month on the corner, but it is still very dangerous and I would hope a more permanent solution could be urgently applied,” he said.

“One of the worst things is the turn off lane into Greenmount Rise – buses pull off but there is no turn off lane and that causes many accidents from rear enders.

“There’s been an improvement since the lowering of speed which clearly demonstrates it would improve even more if the section from Old York Road to Scott Street intersection could be dropped to 60kmh as requested by residents.”

The MRWA spokesperson said the department was not currently considering a further reduction in the speed limit to 60 km/h between Old York Road and Scott Street.

“Main Roads works closely with the Shire of Mundaring,” they said.

“(We provide) technical advice and assistance on a range of traffic management and road safety matters where required, including speed zoning assessments, road safety reviews, traffic management advice, reviews of signs and line markings, and proposals aimed at improving safety for all road users.”
