[U/C] M2 North-South Motorway

[SouthAussie94]

Is this another bridge that will be built down the road a bit, then driven up and put in place one weekend? I think I recall there were going to be two, and only one has been positioned so far.

I can't speak for how the Ayliffes Rd bridge will be built but, the second bridge you refer to will also cross the Southern Expressway, adjacent to the bridge they moved late last year. The second bridge is currently being constructed next to Hungry Jacks

Also, what's up with the six lanes of north bound surface south rd in that pic? Not including the freeway lanes. Surely overkill!

I count 3 northbound lanes: one at the far western side, and two more heading north from the Shepherds Hill Road junction. Where are the other three?

Sorry I meant south bound surface south rd. Two going up Shepherds Hill, two continuing on surface South rd, and two bizarrely turning down to the sunken freeway which they only would have just turned off from.

Yes, but people coming from Tonsley will need to use this entry.

The Ayliffes Road on ramp needs to be there anyway. The next on ramp back would be at Cross Road (there's a list on page 162 of this thread), so any vehicles entering the corridor south of there would be using the on ramp we are looking at. That's businesses and residents near it, and any southbound traffic from Daws Road and Castle Plaza.

So they'll do on and off ramps for Southern Expressway, Flinders Drive and Study Roads and partially for Shepherd's Hill / Ayliffes Road but nothing for the entire stretch between Darlington and Emerson?

Yeah, nah.

[bits]

South Road(Ayliffes) aka end of freeway:
South bound onramp
North bound offramp

Ayliffes Road:
South bound onramp
North bound offramp

Flinders Drive:
South bound onramp
North bound offramp

South Road(Southern expressway) :
South bound offramp
North bound onramp

Eg
-Coming from southern end heading north you can only get on right at the start from South road(south) . I assume you would also be able to get on after Ayliffes also in the future.
-You can get off Flinders Drive, Ayliffes Road and South Road(north).
But maybe not at south road(north) in the future.

-Coming from northern end heading south you can get on from South Road(north), Ayliffes Road and Flinders Drive.
But maybe not South Road(north) in the future.
-Get off at South Road(south).

It seems unlikely to me as well, but remember that access to the corridor will be in locations that serve freight. The completed corridor is not intended to be for commuter purposes.

[[Shuz]]

So if it's intended purpose is freight then it is logical that there would be intersections with Daws Road and one around the Castle Plaza region.

I don't think the Melrose Park/Edwardstown is comparable to Tonsley/Bedford Park area. Billions and billions of dollars difference in types of businesses.

Melrose Park etc also has numerous alternative routes running parallel either side of South Road.

The cattle tracks that is Winston Avenue and Towers Terrace are not suitable alternative routes. Get real.

Funnily enough Towers Terrace or thereabouts was the path of the old MATS N-S Freeway.

There'd surely be an entrance from Daws Road as that would best serve the industry around there. It'll be interesting to see what the government comes up with as the Motorway is intended to be elevated along that stretch.

[bits]

There is Goodwood, Marion and the surface South Road also.
That is 3 majors and 2 minors with a freeway through the middle.

You can't have a freeway with on and off ramps every 100m. Darlington is super excessive as it is, but has single destinations you need to get to. That area is special with a large uni, large public hospital, large private hospital, large police station and numerous large companies.

Wingfield is already a massively larger industrial area than Melrose Park/Edwardstown and still has huge amount of land to grow more. Look to there for what a larger area has for on/off ramp access.

On/off ramps at Darlington and Emerson will easily handle the industry inbetween.

Cue community opposition and outrage if there's no interchanges. 5km without getting on or off is a bit ridiculous. What about in the event of an emergency? Is everyone just gonna be stuck in the trench or overpass? It's unsafe to have a traffic jam of 5km long in the event there's an incident close to either end which obstructs the flow of the freeway.

Melbourne's M1 (Monash Freeway) has interchanges every 1.5km - 2km. This is reasonable and appropriate.

Between Port Road and Anzac Hwy its about 5.75km.

Richmond Rd to Anzac Hwy is about 2.3km.
Port Road to Henley Beach rd is about 2.5km.
Roughly about 900m between Henley Beach and Sir Don.
There's a section on the Eastern Freeway with on/off ramps with only about 700m between them.

I think without question there needs to be and will be on/off ramps at Sir Donald Bradman drive due to the Airport.
Henley Beach road...who knows..there's no much room there. Heritage listed Thebarton theater and former council chambers, and a bit further south on the same west side just past the BP, there's another heritage building. School that's undergone multi million dollar redevelopment on the other side, and the gold store. Something could be done with a realignment of Henley Beach road through there perhaps..

The last post on page 161 quotes the strategy

"The non-stop Motorway component of the North-South Corridor will be directly connected to
intersecting arterial roads via interchanges located at Regency Road, Port Road/Grange Road/
Manton Street, Sir Donald Bradman Drive/James Congdon Drive, Anzac Highway, Cross Road,
Ayliffes Road /Shepherds Hill Road and Sturt Road. "

There are of course other interchanges on the corridor further north and south than the section described there, but that is quoting a 2014 document.
