Aussie Motorway

Any one looked at the single carriageway motorway in Austrailia ?

You can find it on google earth......

Erm, there's a lot of Australia to look at - any clues on where it is?

Also, shouldn't this have been put into the International Roads thread?

Topic moved,

Is this the M2 you're talking about around Adelaide?

This is the world's only truly reversible tidal flow motorway, as it runs in different directions depending on the time of day.

You mean the M2 is a one way motorway? Or there are extra lanes opened in the direction needed?

The motorway is one way at any time the flow being reversed as and when required - ie city bound in the morning and suburb bound in the afternoon - it works well but this is due to I presume the relatively low traffic flows on the reverse flow each day.

The motorway from the satellite pictures shows some interesting junction designs and the motorway itself is generally 2 or three lanes with a shoulder on both sides.

How do they change the traffic flow? Do they have to completely close the road, let the traffic clear, then change whatever signs need changing, and reopen the road in the opposite direction?

I would imagine that the signage is dealt with using Variable Message Signs. Having just toured the length of it on Google Maps, I think they would have to clear the length of it before reopening it in the other direction.

The intermediate junctions are clever. The slip roads are also reversable. Therefore at certain times of the day you would have a right hand exit which becomes a left hand entry when the flow is reversed. These lead to a roundabout where traffic is guided to the correct side of the splitter islands, and thus back onto the conventional road network.

The signs are VMS, yes, you can find photos if you know where to google.

Remember it's the M2 Southern Expressway, Adelaide.

Can anyone post any pictures of this road in SABRE?

It is pretty weird, but not without any common sense ...

Won't it be best to simply build another carriageway of the motorway?

It might be done sometime in the future.
If there were a budget cut for the project, they found this alternate solution to get traffic moving.

Hi folks,

I recently returned from a trip to Aus, and remember fondly a stretch of 'Motorway' north of Brissy that was a single carriageway, with a central reservation. You couldn't overtake, the speed limit was 100kph (60mph) and the junctions were very bizarre.

It's called the 'Sunshine Motorway'.

Here:
bizarre huh?

Here's the google sat link...

Crazy. Have a good look at the length of the whole road. Bizarre happenings...

Very nice roundabout on the motorway at the northern terminus, after which it becomes the Emu Mountain Arterial Road.

Someone has a map showing the global motorway network in Australia

Bit of a contradiction there - a single carriageway with a central reservation means it's a dual carriageway. The term refers to the road surface, divided or undivided, not the number of lanes.

Fair enough...

But I think you know exactly what I was getting at

A D1M. (Dual carriageway motorway, single lane.)

Those who were curious enough to want to see photos of the reversible M2 in Adelaide should seriously consider clicking here.
