Canning Bridge is a traffic bridge which is the most downstream crossing of the Canning River in the city of Perth, Western Australia. The bridge is a part of Canning Highway, and it connects the suburbs of Como and Applecross. The Canning River is approximately 100 metres (328 ft) wide at the crossing, the narrowest point of the river along its downstream stretch. It is located near the Canning Bridge railway station.
There have been four different structures at the present site.
The first bridge was designed in 1846 by Henry Trigg, then Superintendent of Public Works. The bridge as designed was 520 feet (175 m) long and 12 feet (4 m) wide. It had a central span of 24 feet (8 m), and its deck sat just 8 feet (2 m) above the river water.



Construction on the bridge was not commenced until 1849 because the original tenders were too costly. The bridge was built by Solomon Cook, costing £425. The bridge served as a vital traffic link between Fremantle, Perth and Guildford.
The second bridge in 1867 saw Flooding in the Swan and Canning Rivers in 1862 damaged the Canning and Helena Bridges, as well as The Causeway. As a result, a new Canning Bridge was built in 1867 by convicts. This second bridge had a clearance of 12 feet (4 m) above the river water; the bridge deck was raised to have a clearance of 18 feet (6 m) in 1892.



Due to poor maintenance, the second bridge slowly deteriorated. A fire damaged the structure, and since the road served as a critical traffic link, funding was provided for a new Third bridge in 1907 and 1908. The new bridge was built in 1908 at a cost of £2,023, and was a sturdier construction. It was located south east of the present bridge.
The current structure 1939 was a replacement for the third bridge began in 1938. The new bridge, which cost £24,830, was opened in December 1939. It was a timber pile-driven bridge constructed of jarrah, karri and wandoo timber, and features three navigation spans, two of 24 metres and one of 18 metres. It is 175 metres long.
Due to the outbreak of World War II, the third bridge was not immediately demolished, in case of damage to the new bridge by enemy attack. The third bridge was kept in place until the late 1940s.
The 1939 bridge remains standing today, however it has been extensively modified since it was first opened and only carries Eastbound traffic on Canning Highway. In 1958, another pile-driven timber bridge was constructed alongside the existing 1939 bridge on its upstream (Southern) side, effectively doubling the traffic capacity of the structure. This newer structure featured a fishing platform below, but in most other respects was very similar to the original carriageway.







1958 saw the shortening of the 1939 (downstream) bridge on its Eastern end by 3 spans to accommodate an on-ramp to the then-new Kwinana Freeway. Then, between 1965 and 1966, both the downstream and upstream bridges were widened on their outer sides by an extra 2 piles, to give a total of 8 piles per pier on each bridge. At this time, the fishing platform underneath the 1958 (upstream) bridge was also extended and modified.
1976 saw the installation of a reinforced concrete overlay onto the 1939 (downstream) bridge's deck, and the same was performed on the 1958 (upstream) bridge in 1984. The original karri timber halfcaps in the 1939 bridge's structure were replaced by steel in 1994-1995 due to termite damage. Other substructure repairs were also carried out at this time, and the Eastern abutment of the 1958 bridge was reinforced with concrete.
In 1997, the reinforced concrete overlay on the bridge decks was replaced, and was expected to help lengthen the lifespan of the structure by 40 years. Further reinforced concrete was used in 1998-1999 to stop further damage to the bridge's superstructure.

Thanks Doug. I caught my first fish off that bridge in 1972 so it has a special place in my memories.

Morning Doug,

Interesting as always.
I might get to see that bridge one of these days as a trip to the west is in the bucket list.

There are two highlights every Sunday. One is Macca on the radio and the other is the Sunday History Photo on ExplorOz.

Thanks again Doug, greatly appreciated.
All the best, Bruce.

I forgot all about your radio show. Sorry mate.
Where do I find it on the net and what times there or is it a live feed.?

Port Macquarie is a bit far for the radio waves to go from Orange.

Cheers, Bruce.
