Reading through the article myself, to be honest, I think it's written to be informal about the construction of the city loop and provide people with the fresh idea and awareness of the challenges that will come and have to be managed to construct the Metro Rail Tunnel.
The passage begins by saying the disruptions were caused, however that is everything it says about disruption from then on, the rest of the passage indicates Premier Andrew's statement of disruption there will need to be there for safety. Most of the body talks about some of the construction methods that were used.
The passage with the hyperlink 'originally uncovered last year' links to another summarised documentary of city loop construction, with brief passages about the construction stages and images. The paragraph this is in is what I think was used to speak out against, if I should say immature and ridiculous the statements from the former politicians that 'divide Melbourne worse than the berlin wall' and 'your going to see years of disruption' are. The pictures showing diversions date back to the 1970s and 80s and they do present that it was managed very well. We've built the city loop with the diversions that were put in place to maintain safety to the public and they managed, and now we have this benefit just like 712m says above, what if we didn't have the city loop? How would Melbourne function?
There isn't anything in the article to suggest the city loop's necessary disruptions for safety caused unacceptable disruption, everything depicted was prepared in advance and the temporary alterations in traffic flow were managed accordingly.
The last few paragraphs state the city loop construction time period expectations and their completion. It ends with the statement of the Metro Rail Tunnel's scheduled construction start date and it's opening.
It hasn't said anything to imply the disruption for city loop construction was bad, only the amount and it was manageable, it's likely to be written up to inform us a general basic idea of what was necessary to ensure it was delivered on time and minimizing the risk to danger and hazard, as we all need to be informed that Metro Rail Tunnel has to arrange these diversions. Yes there are more people in the state and cars, but we can manage it, and as long as everybody is considerate and being responsible for the tasks they are assigned to it will be opened and the people of Melbourne will benefit.
Articles like these are good in going into the history and bringing out this information where we can be encouraged to look back on it and see how the information it provides to us applies today in the present age. They also help neutralize unintelligent and politically motivated agendas that interfere with the responsible governing and the progress of maintaining, developing and advancing society.
