I think it’s likely a mistake.

Any ideas where TBM Meg currently is? Metro tunnel website is always tardy in providing digging distance updates- and then. suddenly the TBM arrives.

Somewhere between Parkville and State Library, officially due sometime "early January" but, as you  say, the updates are virtually worthless

Yes meg is still 'stuck' at 554 metres  (about halfway) the past week but map suggests it is much closer to State Library. I expect a breakthrough this week sometime.

Millie has moved; now at 156m from ANZAC, so you may well be right about a break through. There does seem to be some desire to make break-thru's 'news-worth' by hiding the TBM's location in the final stretch. They've done it a number of times now

I have just found a letter from Jacinta's office to myself in response to a question I sent her last year.  The government is now confirming the Metro Tunnel 1 has been designed and is being built for a future connection to MMT2.   Therefore the route for MM2 must already be confirmed at least at the planning and government level.

I wonder how they'd interact with each other given that they go in completely different directions?

The route has not been planned, but the network plan has it going via Parkville, and thus Parkville has been designed with passive provision for future escalators to be installed to get to additional platforms.

The passive provision can be seen in this early plan here, things may have been revised during construction and not yet made public.

You just figured this out now in 2021, Parkville station has been designed with a future connection to MMT2 from the beginning of the planning of the project back in 2015.

It doesn't mean MMT2 is planned out yet or ever is going to built anytime soon, but provision is provided whenever they do build it, since the proposed interchange was always going to be at Parkville.

TBM Alice has just launched northward, tailing Millie, towards Town Hall

Alice

Get Meg to State Library and only one length of the tunnels are yet to be started, i.e. State Library to Town Hall

Meg is probably there even though not officially or on the TBM tracker. Metro tunnels website did say it would arrive at the end of Jan but no word yet. I do wish they had a real time tracker not the vague one on the website but I get the need for tiresome media spin.

Yet another update

Tunnelling will be completed by the end of this year if it keeps up at this pace. Smile

I don't know what Bevans 'update' news is because all I see is a rotating circle. If it relates to TBMs at State Library then this is redundant, since Joan is two days into its journey to Town Hall and Meg arrived at State Library today.

It's going to be a busy time at Town hall when they all start arriving within weeks of each other and the retrieval and disassembly begins. Good work by all involved- hoping the city sections go ok. I understand tunnelling will be slower to minimise vibration to the streets and buildings nearby and above in the CBD.

If the TBMs heading south from State Library are ~200m long, they only need to 3 and a bit lengths and they'll be at Town Hall (google maps says La Trobe Street to Collins Street is 693 metres).

HUN is reporting trains will be running sooner.

Metro rail tunnel CBD sites set to stay closed for longer so trains can run sooner

Busy CBD landmarks will remain closed until at least 2024 in a bid to get the [color=#0f5257][size=2][font=segoe ui", "helvetica neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "fira sans", "droid sans", sans-serif]Melbourne Metro rail tunnel[/font][/size][/color] opened to passengers early. A deal thrashed out between contractors and the Andrews government would see Metro builders given access to Federation Square until 2025, while City Square would remain a construction site until 2024.

Some sites had been set to reopen next year while work was going on beneath them, but the [color=#0f5257][size=2][font=segoe ui", "helvetica neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "fira sans", "droid sans", sans-serif]construction schedule[/font][/size][/color] has been flipped to enable better access to work areas underground.

The trade-off means priority will now be given to getting rail and station works finished first, with the above-ground elements of the project done last so that trains can run sooner — potentially by 2024.

A deal on the construction schedule shift came when the builder, which includes Lendlease, John Holland, and Bouygues Construction, agreed to split $2.7bn in cost overruns with the Andrews government. Other sites affected include St Kilda Road, Grattan Street, and Franklin and A’Beckett streets — all to reopen in 2024.

Not surprised at all. Jacinta Allan was already hinting this earlier, about the time when they announced the cost blowouts of the project, they probably made a deal with the contractors to deliver it early.

True it isn't far but my understanding was that tunnelling would be slowed down in the CBD area to check for building movement above. maybe only 5 metres per day ?

Maybe the thinking is that given the city is still so quiet, pushing through a longer closure of CBD sites doesn't cost much politically at the moment, compared to the payoff of finishing sooner?
