"The shortest distance between two points is a straight line"
OK, here's something I don't really follow. If you draw a line directly from the end of the Eastern Freeway to the start fo the Tullamarine tollfreeway it pretty-much just follows straight on. (Under the cemetary, and through the guys of Royal Park. But then, you have to do a pretty decent deviation from there for it to meet J J Holland Park. And then, depending upon which final exit point they pick, it needs to go back up North again, directly after Holland Park so that it meets with Ballarat Road. So... it looks like it's deviating JUST TO GO THROUGH THE PARK - so they can use it as a quarry staging point for 5-8 years.
