At this rate I hope all the 180 crossings are removed from Melbourne by 2050, just as the suburban rail loop opens up.
You don't think you may be getting just a tad ahead of yourself?
What the government are doing just now is fantastic. This level of investment in the network is unprecedented, to assume that it will just continue unabated for the next 30 years is optimistic to say the least.
If Labor follow through (there is nothing to suggest they won't) and they manage to stay in power for 3 terms (which is a good chance) then we can likely expect them to remove 75 to 80 crossings in that time.
Then we start to get into difficult territory. At the moment this project does not have bipartisan support, meaning if or when the Liberal National Coalition get back into No. 1 Treasury Place, then unless they have a major policy shift, they will pull the plug on this whole thing.
Watsons Rd Sunbury, Giffard St Williamstown, Wilson Rd Wattle Glen. None of them see enough traffic to be considered congested or dangerous (the governments catch-cry regarding all crossings they have removed to date) and if the booms at these crossings were down for any longer than they already are I doubt anybody would notice or care, yet they all are on roads that can not afford to be closed. I would suggest they are best kept as they are and there are plenty of others in the same boat.
Then there are other crossings that are just too difficult, like the two on Macaulay Rd, the humdinger at South Rd, Brighton Beach or Ramsden St in Clifton Hill. These and many others like them present very difficult challenges from both a political point of view (NIMBYism) and an engineering standpoint. Again, best left alone, especially when there are plenty out there that don't present the same challenge.
And all of that is without even considering the financial cost with removing all crossings while also building Metro 1, Airport rail, Metro 2, electrification extensions to Wyndham Vale, Melton, Wallan, Clyde and Baxter, and of course the whizz bang SRL. Oh yeah, and high speed rail to Geelong and Ballarat.
Again, 50 crossings in 8 years is a massive undertaking, 75 in 12 years will be outstanding. Then to achieve all of that as well as the other stuff I just mentioned, we can expect to have more invested in Heavy Rail in the greater Melbourne area then we have had in 100 years.
Providing it all gets built that is.
