M1 South-Eastern Freeway

[Norman]

I noticed yesterday when driving through that the new variable speed limit signs in the tunnel and on the approaches are bidirectional, ie they are on both sides of the gantry. You can see this in the renders if you look close enough.

Presumably this is so they can close one tunnel off during and emergency and also when they are doing maintenance and go contraflow.

Interesting, good pick up!

Channel 7 and InDaily reporting that a band-aid solution has been devised, with traffic lights to be moved 100m west along Cross Road.

Why not just install a concrete barrier in the median strip of Cross Rd?

Sure, this wouldn't stop traffic heading west on Cross Rd from being hit by an out of control truck, but neither would moving the stop line for the intersection further east.

There's probably not enough concrete in all of South Australia to build a wall thick and tall enough to stop a runaway truck.


IMO, as a truck driver who descends the freeway once or twice a month, there's nothing that can be done to fix the problem with the intersection in its current configuration.

An arrestor bed wouldn't have saved that last truck from rolling.. He just took the left turn way too fast, could have happened at any other intersection.

I see more smoking brakes going down Grand Junction road towards the Gepps Cross intersection than going down the freeway

The existing median is about 2m wide.

A 2m wide, 1m tall barrier would surely be as truck proof as you can get. Obviously wouldn't be great for the poor driver of anything that hit it though.

I guess this just leads to the discussion thats happened countless times in the past. What's the long term plan for the intersection and the freight route from Murray Bridge to Adelaide?
