What will the route number configuration be like once WestConnex is finished? (predictions)

[DrazPhlaz]

When westconnex is complete, it will have an enormous continuous tunnel linking the M4 to M5. Out of curiosity I'm just trying to imagine how that would work in terms of route numbers. Would M4 terminate at it's junction with the original M5? Would the A4 route continue along it's current path and the tunnel be given no number? There's many options but none seem very sensible

[Sam Laybutt]

The north-south component of Westconnex may well have the same number as the Western Harbour Tunnel and beaches Link/Wakehurst Parkway. Could be M10/A10?

Hmm I didn't think of that, that could possibly work, although it's unlikely they'll think of that

[Brendan Terrett]

I think it'll be two separate route numbers, mainly because of the eventual hooking up of the F6 extension at Tempe. Presumably the F6 extension will be given the M1 route number, but there's no plans for any east facing ramps to hook up with General Holmes Drive, so by that deduction the route will probably have to go through the Westconnex north-south tunnel to hook up with the M1 at Cammeray.

I think the Beaches Link component will be numbered M8 from Wakehurst Parkway to the Warringah Freeway, with the Western Harbour Tunnel and WCX Stage 3 being given M10 as an interim measure until they can hook up the F6.

Then when the F6 is hooked up, M10 will become M1. Though I do wonder what route number they'd give Southern Cross Drive/Eastern Distributor/General Holmes Drive. Perhaps they could extend M8 down there to make it all line up nicely?

Good points - assuming the F6 is M1 then M1 should continue up the Western Harbour Tunnel as this is the 'bypass' route (although do we see the 'Iron Cove Link' eventually becoming a tunnel to Wahroonga?)

M5 could be extended up Southern Cross Drive and through the City to Cammeray - or the CCT/SHB/SHT triangle could be the terminus of M4/M5/M8. 

A few options, not many of which make a huge amount of sense at this stage. 

I'm not sure M8 would be appropriate for the Beaches Link unless the current A8 was renumbered. Beaches Link and the Frenchs Forest hospital should surely cement Wakehurst Parkway as the primary north-south route on the beaches.

I agree that it's better for it to gain M1. But we don't know that no east facing F6 corridor ramps will exist - that's simply not designed. The only thing within the scope of WestConnex is the stubs to join the M4-M5 link, and I suppose also the omission of stubs for any west-facing junction. Both east- and west-facing movements need to be provided in some way shape or form because heavy vehicle destinations from the Illawarra will significantly skew to Port Botany, Chullora/Enfield and Moorebank.

[Richard Ho]

Here's my hypothesis:

• What is currently A4 between Concord Rd and White Bay will be renumbered A44
  
• The M4 to M5 link will become an extension of A40 and be numbered M40. The duplicate M5 tunnel will also form a glorified feeder ramp to the M5 westbound
• M5 remains as is
• The Western Distributor will become a component of the M4 corridor, thus making the former Metroad 4 fully motorway/grade separated standard.
• M1 will be extended onto the proposed F6 corridor. A36 would be extended south to Waterfall replacing A1 on the Princes Hwy through the Sutherland Shire.

[Tom H]

I doubt they'd go with M40. While the route connects nicely with A40 today, the intent is that it will eventually link seamlessly to the Western Harbour Tunnel and Beaches Link, which is entirely the opposite direction of the A40.

I'm also wondering what routes and names will go to "New M5" versus "M5 East". If both routes have M5 in their names but only one has the M5 route number, there will be face palms a'plenty. I'd hope the "New M5" name will never appear on signs.

[Brendan Terrett]

This is how I suspect the routing signage will evolve as the stages open (looking from the Gardeners Road entry/exit)

*pls excuse QMR-esque design, but you should get the idea

2019 - Opening of "New M5"

2023 - Opening of M4 to M5 link

2026(?) Opening of Western Harbour Tunnel/Beaches Link

Eventually... the F6 connection hooked up

@Brendan Impressive signs, I think they look pretty reasonable. However, Save M10 for the old M1 route past the airport to ED and the tunnel

In the end the best option would look something like this. Black is existing roads

M4 will continue its current route, as will M5. Old M1 will be replaced by M10, The north beach tunnel will be M8, and the old spit road will be any other number (a29 for examples sake). Not sure if a 2nd northconnex linking gore hill fwy to the newcastle m1 will be in the cards, but for this map the traffic coming down from north on the gore hill will have priority lanes to exit onto the new western M1 tunnel. (the whole north sydney interchange will need to be revamped to do anything)

One thing that hasn't been mentioned - what happens between the St Peters interchange and the CBD? 

With Euston Road being the main traffic route to the inner suburbs, does it get a route number?

If yes, does it go up through Redfern to Broadway and/or the Western Distributor like the old SR66? Or does it go east across towards Randwick?

[DrazPhlaz]

Maybe two routes can spawn from that interchange. One A route up to the city and one A route out east, looping back around to the cct

[davis]

No other numbered route for it to terminate at, so no route number?

[Sam Laybutt]

The Broadway option could terminate at A22 (or more sensibly A4), the eastern option could terminate South Dowling St (To M1)?

The Euston Road corridor to Broadway is really short and it closely parallels A36. It could extend further north to meet the Western Distributor.

The Campbell Rd / Gardeners Rd corridor could have a number, but to where? There is a real lack of route numbers in the Eastern suburbs.

I drove from the M4 through the tunnel and exited at the St Peters interchange yesterday. Heading east near the Haberfield exit "M4" is painted on the road surface whilst at the moment has M8 Airport / Port Botany on road signage.

Obviously the road signage makes sense until the Rozelle interchange is open.

I haven't gone in the opposite direction yet from St Peters to Haberfield and further west. Technically it would be M8 Motorway but wouldn't be surprised if at this point the road signage says M4.
