Government tender documents have revealed corrosion and termite problems on the Fremantle Traffic Bridge, sparking fresh calls for the bridge to be replaced.
The documents, lodged by Main Roads, are for "preventive and specific" bridge maintenance.
The papers say "badly corroded" metal straps around bridge pylons must be treated and tightened, active termite infestations must be treated and more than 20 timber bridge bearers must be fixed.
Two years ago, The West Australian revealed that a previously secret engineering report from 2004 had found the bridge was approaching the end of its serviceable life, with an unacceptably high risk of collapse and multiple fatalities if it was hit by a vessel.
The report, commissioned by Main Roads and done by local engineering consultants Shawmac Pty Ltd, described the risk of doing nothing to replace or upgrade the predominately timber bridge as "intolerable".
It said the risk of the bridge collapsing from being hit by a vessel was 66 times above accepted standards.
Fremantle MP Simone McGurk said replacing the bridge should be a priority.
"Nine years ago, the assessment was that this bridge needed to be replaced," she said. "This is a major piece of metropolitan infrastructure with thousands of car and truck movements every day, yet we are looking at band-aid repairs and no allocation for a replacement."
Acting Transport Minister Mike Nahan said the bridge was safe and Main Roads was working to ensure its safety and integrity."The tender is for routine maintenance of the bridge - to apply a termite protection treatment and an anti-corrosion treatment," he said. "This is standard maintenance for all timber bridges that is undertaken periodically."
