ah but gweg, you said 4 x that they were doing it as a cost cutting exercise.
Correct.
I'll say it a 5th, if you like.
Maintaining a WRSB is
very expensive.
Every time a vehicle hits the barrier, it costs many hundreds, if not thousands, of dollars to repair.
The posts are designed to collapse on impact, and they must be replaced every time they're hit.
Moreover, the wire rope itself stretches and also needs to be replaced, or at the very minimum retensioned, after a hit from a vehicle.
These components are expensive, and the labour isn't provided for free.
Conversely, when a vehicle hits a
concrete barrier, there is usually no need for any maintenance at all (other than maybe pushing a block back into place).
Now, if there's anything else you need to know about this subject (which you quite clearly know next to nothing about), feel free to ask me.
I'm here to help.
Again, I hope this poor little girl's family finds peace soon.
