Carmageddon on WA roads

Major roads struggling to cope with increased traffic volumes have been identified as the State's most dangerous.

WA's biggest road infrastructure community survey - run by the RAC with _The West Australian _ - received more than 5000 nominations for the State's most dangerous roads and intersections.

Gnangara Road - specifically the intersection with Beechboro Road - topped the list.

"It's a nightmare," Ellenbrook resident Lois MacDonald said. "It's terribly congested all the time."

Another Ellenbrook resident, Kathy Davidson, said: "I cringe every time I have to drive through that intersection. It's a dangerous stretch of road.

"They've put some lights in but that hasn't stopped the accidents.

"There are accidents there all the time."

Other roads rated high-risk included Bussell Highway in Capel and Beechboro Road North in Cullacabardee.

Some of the other worst intersections were Ocean Reef Road/Edgewater Drive in Edgewater, Ennis Avenue/Port Kennedy Drive in Port Kennedy and Mandurah Road/Surf Drive in Secret Harbour.

The Risky Roads survey found that many nominated sites involved right-hand turns on to roads with high-traffic volumes travelling at significant speed.

There was also a big increase in the number of drivers who were confused by intersection designs and lane markings.

For example, the Ennis Avenue and Mandurah Road intersection where school crossing "stop" lines were installed inside a four-way intersection had caused concern.

Most nominations were from the metropolitan area but there was a significant number from the Wheatbelt, where the survey report found there was a "worrying increase in the number of complaints regarding heavy haulage".

"Respondents made repeated references to the increased number of trucks because of the closure of the Tier 3 rail lines and the perceived safety issues associated with the freight task," it said.

RAC general manager corporate affairs Will Golsby said the survey highlighted the urgent need for more road funding.

After the previous Risky Roads survey in 2011, work was commissioned for nine of the top 10 nominated roads.
