Cheers mate. That's the first I've heard of that and it will make everything a lot easier.
I'm not saying it isn't true but a bridge over the freeway will cost massive dollars.
It sounds like it would only be less than one kilometre north of the existing overpass of Armadale Rd.
It sounds sensible to do it to relieve congestion but when was the last time the W.A State govt spent money sensibly.
