7 bridge spans turned up this week at Brunswick Junction for the replacement of the railway bridges (5 span + 2 span) between Roelands and Burekup. They are the ballast deck type. For approximately one and a half years there has been a 40kph speed restriction over the bridges for reasons I can only speculate as being due to the sleeper condition on the bridges. I do not know if there are structural issues with the steel work but I would think not. I do not know when they will be replaced exactly but it will happen sooner then later. So get your photos while you can. The old South Western Highway alignment adjacent the bridges affords an easy time finding locations to take photos. Please note tresspass laws where applicable.
Testing the brain cells out, the original bridge is a transom deck bridge (correct?).
The issue was the bridge was designed as a standard gauge bridge. The transoms laid with the NG rails that put a moment through the transom and not a direct transfer of mass from the rail being above the bridge beam.
So maybe the deck upgrade is part of removing the transom issues.
