The Liberal National Government will undertake a $3 million maintenance upgrade on the Fremantle Traffic Bridge to ensure the safety and longevity of the structure.
Transport Minister Bill Marmion said a contract for underwater pile repairs had been awarded, with most of the work taking place underwater using a team of specialist divers working off a barge.
"Works have already commenced to ensure the long-term and safe use of the bridge, by repairing more than 100 piles," Mr Marmion said.
"Main Roads WA has recently completed a series of pier protection works on the bridge's fender system, and is now focused on strengthening the bridge piles in the Swan River.
"Our key concern is ensuring the safety of motorists and the continued flow of traffic across this important bridge."
Fremantle Traffic Bridge provides a direct transport route from North Fremantle to the Fremantle central business district. The bridge is used by about 28,000 vehicles and several hundred cyclists each day.
The project is due for completion in May 2017.
Fremantle Traffic Bridge was constructed in 1938 and is one of two important road traffic links across the Swan River in Fremantle
Any navigation channel closures required for the works will be advertised as a temporary notice to mariners by the Department of Transport
Advanteering Civil Engineers have been awarded the contract for the piling works
