I used to live at 2-4 Hereford Street years ago and experienced the rise of the Macquarie River many times.

Sometimes it was just by a few feet, but it was enough to cause problems with traffic.

When the new bridge was built some years later, I found that the low level bridge remained a "low level" bridge, to my surprise.

In future, please make sure that the bottom of the next bridge, to be built, will clear the highest previous reading of the river in flood by a suitable distance.
