Why? Is it because of the pylons not being able to take enough weight, or something else?

no, it would probably look stupid and given all the protests etc against skyrail the first time, it would be a bad idea to repeat all of that

The pylons would have been designed to take the expected weight and dynamic loads of the existing bridge deck. They wouldn't have been designed to take double that load, that would have just bumped up the cost, possibly significantly.

The pylons would have only been designed to take an extra deck if there was an expectation that soon a 2nd deck would be required. Even then it would have been a hard sell to get the extra expense of the stronger pylons approved. Projects don't like paying for future 'maybes'.

Thanks for the clarification. I should probably stop going on about this but is it possible to strengthen the pylons. If so, would that be a viable alternative to property acquisition in what is an inevitable project?

I don't know how your second deck Idea would work ?

You would need additional piles and a substantial steel superstructure to hold the second deck above the existing viaduct deck (that would drive the local NIMBY's out of their mind)

Property acquisition Is the only solution (reason why the Government has started to buy up properties)

It probably is cheaper to acquire more properties and build a 2nd single deck bridge alongside than try to re-engineer an existing structure to be two layered.

I don't see any problem with the construction ideas.

Which option is going to get chosen
Feds want heavy rail while Andrews has proposed light rail

No Capacity on the Dandenong Line so the Rowville Line would have to run from Oakleigh to Alamein via Chadstone, if it is heavy rail.

Light Rail can work well, just how will it work along the Princes Hwy. Would need traffic light priority Gold Coast Style and new super Trams. IMO, Monash To Caufield works as a brilliant light rail route, not sure about all the way to Rowville though
