At 660 mtrs Mount Henry Bridge is the longest road Bridge in WA. It was completed in 1923 and at that time carried the Kwinana Freeway and Mandurah Railway line across the Canning River. It was widened and strengthened between 2004/6 and as it stands now the original bridge carries the two railway tracks plus three southbound traffic lanes and the added structure carries three northbound traffic lanes. In cross section it is a 'double box' section with the upper deck (including cantilevers) carrying traffic, and cantilevers at the bottom of the box carrying pedestrian/cycle paths. It's not what you would call an elegant or graceful bridge but it is a very impressive solid, strong bridge, it seems to have the seal of approval from this little swallow who followed us all the way across, alighting here and there on the rail as we walked.....!! Hope you have a happy Sunday.....
