Work is expected to start this month to demolish and replace the timber bridge that was built in 1913 with a concrete structure designed by Main Roads WA.
Transport Minister Dean Nalder said replacing the bridge with a new 80-metre contemporary structure with increased load capacity would ensure it met current safety standards.
‘It will allow the Public Transport Authority to add a further two rail lines to the Perth-Midland line,’ he said.
‘It includes improved turning and lane widths, a footpath, bridge guard rails and electrification screens.
‘It will also be complemented by landscaping and public art, which is being developed in consultation with community groups and the City of Bayswater, to recognise the bridge’s local heritage significance.’
The Seventh Avenue bridge contract was part of a $22 million project managed by Main Roads, including the replacement of Third Avenue bridge in Mount Lawley.
Mr Nalder said the project had been staggered to minimise disruption.
‘Work will commence shortly and is expected to take about a year to complete,’ he said.
‘During construction, traffic will be detoured over the railway via the Caledonian Avenue level crossing or Third Avenue bridge.
‘Once the new bridge is fully operational, work will begin on replacing the Third Avenue bridge.
‘This should take a further eight months to complete.’
