Very good points, and the future growth of Hackham, Seaford Heights, Seaford Meadows, Moana, Aldinga and Sellicks Beach is only going to put more pressure on this section of road. Not to mention the increased levels of tourism that McLaren Vale is experiencing too.neoballmon wrote: ↑Wed Aug 02, 2023 12:14 amIt's also worth pointing out just how much growth this area has experienced. When they did the Victor Harbor Road Junction 10ish years ago, the finished works were great and held up capacity!
Prior to that, Victor Harbor Road northbound had one lane turning right through a stop sign, into their own lane. South Road northbound went from 2 lanes to 1, to join with the lane from Victor Harbor Road. This led to 2 lanes at the Seaford Road intersection - which may have actually been better than the merging disaster it is currently.
So anything done here needs to take into account that the area, but Aldinga especially, will continue to grow rapidly!

With all the upgrades hear and there over the years, extending the Southern Expressway to Aldinga might of been a wiser choice . The current section between Griffiths Drive and Aldinga Beach Road will be almost expressway/freeway standard. A simple flyover at the junction of the Southern Expressway/Main South Road. At Seaford Road/Victor Habor junctions the expressway could go over both those junctions, and same for Griffiths Road junction.A-Town wrote: ↑Wed Aug 02, 2023 10:22 amVery good points, and the future growth of Hackham, Seaford Heights, Seaford Meadows, Moana, Aldinga and Sellicks Beach is only going to put more pressure on this section of road.

I recently received notification of a Major Traffic Switch planned for this weekend for the Main South Road Upgrade Project. This switch will see traffic using the new Maslin Beach/Tatachilla Road Overpass for the first time. Maslin Beach Road will also re-open mid September with limited traffic movements onto Main South Road (Left in and Left Out of Maslin Beach Road only).

Driving along Victor Harbor Road this week I was quite astonished to find they’re building a roundabout on the section between Old Noarlunga and McLaren Vale!
Why isn’t that intersection being grade separated?

Your guess is as good as anyone else's, but presumably it's to slow traffic and reduce bottlenecks in the final northern stretch of the road to Main South Road.

I suspect that insufficient traffic volumes from Robinson & Quarry Roads onto Victor Harbor Road meant that the cost of full grade separation wasn't justified. I do think that must have been a pretty close call though.
Having said that, I've been using the roundabout every Saturday since it opened and it certainly has made it much easier to turn right from Robinson road onto Victor Harbor Road towards McLaren Vale, even in its unfinished single lane state. I am unsure however, how that will hold up when peak traffic northbound on Victor Harbor Road occurs, I think getting out of Robinson Road at that time will still be a nightmare, but we'll just have to wait and see.

Current night works in this section should see traffic switch to the new road south of the roundabout within 2 weeks, then a few weeks after that for the Northern half.
Will be great once 2 lanes are open because people just don't know how to drive through this area.

[U/C] Re: Main South Road & Victor Harbor Road Upgrade
Another traffic switch has occurred this morning on Victor Harbor Road, between the new roundabout and McLaren Vale.
It's switched back to the original roadway, presumably so they can lay the final layer on the new alignment, and do other finishing works, such as a sealed shoulder (which has been done on the original alignment prior to it opening today).
Concrete barriers still in place for the majority of the section and line marking at the Seaview intersection look like they're they're long-ish term, so I expect at least a month until it's 2 lanes in each direction.

I also drove the length of South Road last night, and it's progressing quite well. Tatachilla Road bridge is open in one lane each way, and the majority of the corridor has at least base layer laid.
Biggest delay will definitely be the bridge, but I think outside of this, most of the project will start opening up by the end of the year.

I dont understand why they're demolising the old bridge.
I know that it's probably nearing the end of its useful life as a roadway, but surely as a pedestrian/cyclist bridge, it would have another 50 odd years of service! I can think of several bridges that only remain for these uses and haven't seen a car across them for decades.
I know the coast to vines train veers off just before this bridge, but with Aldinga growing, who's to say cycling towards the area won't become more popular, and I doubt the width of the new bridge allows much room, if any, for pedestrians and cyclists.

The new bridge has a wide shared path based on the designs, the old bridge would be insanely wide for a simple pathway.neoballmon wrote: ↑Thu Oct 12, 2023 6:14 pmI dont understand why they're demolising the old bridge.

I think the main factor would be that demolition now while works are ongoing would be much cheaper than demolishing it in a separate project once it reaches end of life as a pathway.

Yeah I did see those photos earlier, I can see the shared path, so demolition makes more sense now. Thanks

A shared use path is great, but if we're to be serious about boosting cycling, then dedicated bike infrastructure is needed over shared use paths.
