INCREASED traffic along Shelley Bridge is causing congestion, frustration, accidents and delays, according to Riverton Rossmoyne and Shelley Residents' Association (RRSRA).
RRSRA secretary Caroline Dunsire said traffic had been steadily increasing for years, with ‘lane-hoppers’ halting traffic.
‘Traffic approaching Shelley Bridge is merged from three lanes to two and if the traffic turning onto Centenary Avenue is heavy, this effectively reduces Shelley Bridge to one lane,’ Ms Dunsire said.
‘This has a flow-on effect and traffic backs up past Vahland Avenue, and at times the intersection can be jammed as vehicles move into the intersection before there is space.’
The Association wants Roe Highway completed, Shelley Bridge widened, with cycle and pedestrian ways, incorporated and a third lane created eastward allowing for a ‘virtual’ dedicated lane into Centenary Avenue.
Its wishlist also comprised pull-in bus bays so traffic was not disrupted and co-ordinated off-ramp lights at Centenary Avenue to reduce peak time backlog on to Leach Highway.
Ms Dunsire said changes were essential.
‘The bridge has been there for a relatively short time and traffic has increased so significantly; consider how it will manage in another 10 years with a further doubling of traffic,’ she said.
Main Roads WA manages Shelley Bridge, which about 60,000 vehicles use each day.
Main Roads spokesman Dean Roberts said traffic was worse during the morning peak for eastbound traffic and in the afternoon peak for westbound traffic on Leach Highway approaching the bridge.
‘Main Roads is currently undertaking project development work on the Shelley Bridge duplication project,’ Mr Roberts said.
‘For projects of this extent, it would generally take three to four years to complete construction.’
Opposition transport spokesman Ken Travers said Riverton MLA Mike Nahan broke an election promise.
Mr Travers said during the 2013 State Election campaign, Dr Nahan promised the Liberals would install more traffic lanes on Shelley Bridge.
‘Extra lanes on the Shelley Bridge would reduce rat runs, yet the Barnett Government has walked away from this election promise,’ Mr Travers said.
Dr Nahan said the Government was committed to widening the bridge and had invested $250,000 to plan and prepare a project business case, which included extra lanes and a bike path.
‘The Government is committed to reducing congestion on both Leach Highway and South Street by building the Perth Freight Link; the Perth Freight Link is the Government’s priority,’Dr Nahan said.
‘In regard to Fern Road, Mr Johnston and Mr Travers fail to understand that Riverton Bridge and Fern Road has always been a heavily used route, given that cars cannot turn right onto Shelley Bridge from Marjorie Avenue.
‘Fern Road has had significant traffic calming and speed bumps installed for years to help moderate and slow traffic down, so this is not a new phenomenon as he proclaims.’
