A new road bridge connecting Station Street to Station Street over the Patterson River is planned.
This can be used as a temporary rail by-pass whilst any changes to the Patterson River rail bridge are completed.
Allowing for a safety fence 3m from the by-pass rail track access to properties either side of Patterson River remain unaffected.
This will require a stronger bridge for the train use but any additional height caused by deeper spans can be accommodated with the more lenient road design rules and/or service road use.
And this is working on a two-track by-pass where train schedules will not have to be altered.
But even with a single-track by-pass all trains can be accommodated ~
This effectively increases the distance from the Patterson River to McLeod Road.
Additionally, the vertical gradient transition from level to – 2% (or more) can be achieved over the
mid spans of the bridge improving the effectiveness of lowering the southern span and not impacting on boat clearance.
