Could some one, any one, please finish to last 20 metres of James Conglon Drive where it meets south rd. How much longer is this going to take???????????????????????????????????

Has anyone noticed a huge increase in congestion on the Salisbury Highway since they've finished the Superway? Every morning it's bumper to bumper from Port Wakefield Road until the PREXY. It wasn't like that before

The Northern Connector will fix that.

Yeah it will, but that congestion didn't exist before the Superway was built

The entire north is rapidly increasing in population. Look to mawson lakes filling, burton area increase, munno para area is massive now, etc.

In 2006, the road carried 48,000 cars per day, then 63,000 in 2012. In 2015 it carried 69,000 cars per day.

Yikes, I didn't realise that there was that big of an increase.
From my perspective the congestion started when they lowered the speed limit from 80(or 90?) back to 60 while the superway was being finished, however when they put the speed limits back the congestion didn't lift

The Northern Connector road alignment plan looks like the works tie in to a 6-lane Salisbury Highway.

Given that the Northern connector itself won't be complete till sometime in 2019, the above between the Superway and PWR might be a possible early works package.

Yessss. My sentiments exactly.

I think the Dept of Transport photocopy boy is in charge of this upgrade. Previously it had the widest median strip in the known universe and now they fail to finish...

Must be one hell of a photocopying backlog...

[neoballmon]

Did anyone head north for the long weekend? How was either the detour around port Wakefield or the traffic at Port Wakefield? Was it any better than usual?

What congestion? Adelaide CBD traffic shrinks



Traffic through Adelaide’s CBD has dropped over the past four years and the take-up of public transport and cycling continues to grow, new figures show.

According to a new Adelaide City Council report, between 2010 and 2015 traffic has reduced:

- 30 per cent on Grenfell Street.
- 25 per cent on Currie Street.
- 15 per cent on West Terrace.
- 8 per cent on North Terrace and Botanic Road.

Overall, daily traffic volumes have reduced along many city streets but increased along the city ring route.

The figures begin to fulfil the long-held ambition of traffic planners to have South Australians travel around the city, rather than through it, on their way to destinations outside the CBD.

During the same period, traffic numbers on the city ring route rose by 13 per cent on Fitzroy Terrace, 12 per cent on Park Terrace and 5 per cent on Dequetteville Terrace.

According to the RAA’s senior manager of road safety, Charles Mountain, the Britannia roundabout upgrade – completed last year – had been a significant factor in pulling through-traffic out of the city and onto the ring route.

“The new (roundabout) has tended to gain wider support, so as a consequence there has been an increase in traffic,” he told InDaily.

“It’s important to ensure that the network can operate as efficiently as possible.”

He said long-term roadworks on North and West terraces may have had an impact on traffic flow.

He was pleased with figures contained within the report showing no slowdown in economic activity to correlate with reduced traffic flows in the CBD.

Bus lanes were introduced on Grenfell and Currie streets in 2012, presumably acting as a deterrent to vehicle traffic.

“The bus lanes in Grenfell and Currie street have achieved more reliability in bus times (however) there certainly have been some issues in loss of accessibility,” said Mountain.

Bus trips to the CBD have also increased – by 29 per cent since 2002 – according Adelaide Metro figures cited in the report.

The report also shows cycling in the CBD has nearly doubled since 2003.

In that year, around 5000 cyclists took city roads on the average day. By 2014, that number had grown to more than 9500 cyclists.

A spokesperson for Adelaide City Council said the figures on CBD and ring route traffic flow come from manual day counts at intersection over a 12 hour period or tube counts – where a counter is laid midblock on a street section for a week. The data has been collated from traffic analyses related to projects such as the O-Bahn, the Frome Street Bikeway, the Hindley Street upgrade, the 40km/hr Hutt Street trial and New Royal Adelaide Hospital. The council spokesperson said the Department of Planning, Transport and Infrastructure applies an algorithm to the data collected to estimate average daily traffic volumes.

He said the majority of traffic volume comparisons undertaken by the council in the north-west and north-east of the city had indicated reduced or similar daily traffic numbers.

Traffic in the city has decreased simply because the number of lanes has been cut back. For Example Hutt St ,Wakefield St, Grote Street, North Tce , Grenfull St and others have all lost one lane. Frome St has been stuffed. The Adelaide City Council took out the right hand turn lanes from Pultney St South.

When did Hutt, Wakefield and Grote Streets lose lanes? And Frome St has been far from stuffed. The traffic volumes even before the bike lanes in didn't necessitate 4 traffic lanes.

Regardless of whether this is the case or not (I'm, not sure it is), I can't see what the issue is - the takeaway point from the article is that traffic flowing *through* the City has decreased, traffic flowing *around* the City has increased, public transport and cycling to the City has increased and overall economic activity in the City hasn't slowed.

So isn't this a win-win-win situation? The city ring route has been upgraded to the extent that it is an attractive alternative to those who would otherwise have cut through the City with no intention to stop there (thus contributing nothing to the overall city economy but impacting traffic congestion and pollution) and meanwhile it doesn't seem to have affected those who intended to travel *to* the City apart from the fact that healthier and more sustainable forms of transport are increasing in popularity.

It seems like a good news article to me...

Did I miss something from the article? The indications seem fairly clear that formalising the ring route, including the improvements to Britannia, are reducing cross town traffic.

Agree that traffic reductions on Grenfell and Currie seem natural given the establishment of bus lanes.

This is all good news, I certainly wouldn't characterise any of the changes as being 'stuffed'.

I think increased cycling numbers are natural as traffic on arterial roads gets worse. At my prior residence (~7km from the city) I switched to cycling once it became quicker than driving. Saving money and losing weight were a nice added bonus.
