Mitchell freeway southbound road noise from one line!!

I know this is basically a shit post, but does anyone know what I’m talking about?

What used to be the far left lane (now middle left or just middle) there’s this “line” that’s either cutting into the road or damaged into the road that creates a lot of road noise when you roll over it!!!!

It’s not a straight line it goes all over the place so I’ve often wondered if it was just caused by some prick who damaged the freeway from around Clarkson all the way down to the city!?!

Surely I’m not the only one that knows what I’m talking about 😬
