Silly main road design

By JC - 7 February 2012 45

Who is it in ACT roads that comes up with new road designs? Drove through Molonglo the other day along Cotter Road to discover that the alignment has changed and it now heads through the middle of the two new suburbs of Wright and Coombs towards Uriarra road. To get to the Cotter and suburbs such as Duffy a left turn is now required into Cotter Road. I assume at some point the road from Adelaide Ave to the new turn off will be renamed something else otherwise it will be odd having a road change name with a left hand turn.

Anyway the alignment and new arrangement makes sense, but what doesn’t is the fact that this road, which is clearly a major feeder road has those silly side roads coming off it, presumably with high density housing to be put alongside. Surrey if this is a major road why have any small side streets off it? Why not do what was done in the older suburbs and have one or two roads leading into the suburb and have every other road feed off these? Why do we need minor roads like this coming off a main road? They could still build all the high density housing they wish without these silly minor roads coming off the major road.

Out Gungahlin way they have done the same thing along Flemington Road and Gundaroo Drive between Horse Park and Mirrabei Drive, again both roads that by rights should be major thoroughfares.

Anyway have a look at these Nearmap pics. First showing the new arrangement in Molonglo.

Then Gundaroo Drive in Gungalin. Isn’t it plain to see that it would have been better for Gundaroo Drive to continue as a main road to Horse Park Drive? Now everyone who lives north of Horse Park Drive will need to come through the middle of a residential area to get to the town centre. Plain stupidity.

And finally Flemington Road. Again pointless having these piddly roads off what should be a main road. The alignment should have also ended up running onto Mirrabei as a main road instead of feeding into the main shopping/pedestrian area of Gungahlin.

Oh one last thing why are all left turns at lights now being built with such hard lefts, whereas in the past they were a lot gentler?

What’s Your opinion?

You can simply click the checkbox and click the button for ‘personal use’, no signup required. One advantage of nearmap is that it is updated every few months, so you can alternate between previous images, great for watching developments such as these.

Unfortunately for dvaey it doesn’t fit into his anti cycling agenda but i think the hard lefts are there to make people turning into a road do it at a slower speed.

How exactly is turning onto an 80km/hr road from a slip-lane at a ‘slower speed’ a safe situation? The hard left turn causes a number of problems, firstly it means you can no longer use your mirrors to check oncoming traffic, or easily headcheck as the angle of the sliplane puts oncoming traffic into your blindspot. Another side effect of sharper turns on slip-lanes means that where a slip-lane used to be able more than half a dozen cars, they can now fit 2 or 3. It also means where you previously had 100m+ to match the speed of other traffic before merging, you now have about 20m.

forget about the traffic lights – why isn’t Cotter road at least two lanes each way by now? Nobody anticipates the future traffic!

or William Hovell Drive (Kangaroo Alley – as I like to call it)

You obviously have never driven to Cann River from Canberra. At Cooma you turn left off the Monaro Hwy onto the Monaro Hwy and then after you stop for the best in the region at Nimmitabel you turn right off the Monaro Hwy onto the Monaro Hwy.

Whatt annoys me more about the new cotter rd / john gorton drive alignment is that RoadACT insisted on pushing the road 100m further south than the original alignment, cutting in into the already tiny buffer zone bw weston creek and molonglo

Talk about a land grab! I’m still angry about this incursion into weston creek territory – like molonglo doesn’t already have enough land to sell off!!

At the time they said it was simply not feasible from an engineering perspective to build it any other way, but clearly this wasn’t true as the terrain is flat and hardly insurmountable (the project was brought to you by the same people to dig a lake out of asbestos, a much bigger and more expensive task)

The terrain is flat? What planet are you living on?

Plus I’m not sure why you are bothered about minor roads coming off major roads. What’s the point of a major road if it doesn’t connect to anything?

You just have to check an ‘I agree’ checkbox, then click ‘take me to the map’ at the bottom. Hardly signing up…

As far as I can see the government is trying to create transport hubs along these feeder roads which have high density housing built along them to enable higher use of public transport.
As well as this, a lot of these developments are going to be mixed use with commercial shops/restaurants etc on the bottom floor/s with residential above, so the service roads enable people to find and use these businesses.
The road in Molonglo is going to be John Gorton Drive which I think is going to be built similar to Flemington road.

Up to you if you don’t want to join near maps, it is actually quite an interesting site and a shite load better (updated very regularly) for Australia than Google maps and free.

Anyway what I am talking about is not minor roads coming off a major road of course that is quite normal, what I was talking about are side roads, read service roads, these are silly roads that run parallel to the main road to service housing directly on the side of the main road. They are one way streets that veer off and join the main road at regular intervals, whereas the minor roads come off at cross or T intersections or roundabouts.

Anyway my main point being why have housing fronting what is going to be a major through road. Why not have the housing in the exact same place but backing the main road with the service road being on the other side, like they did it in the past? If they want the housing to front the main road why not build them “backwards”, like they have done elsewhere and keep the part fronting the main road as a pedestrian area and the back where the road is. It will be a hell of a lot safer.

Here is a link to what I am talking about on googlemaps, in this case Flemmington Road.

Unfortunately for dvaey it doesn’t fit into his anti cycling agenda but i think the hard lefts are there to make people turning into a road do it at a slower speed. In fact I think many of the cycle lanes in this city are there to make drivers slow down rather than help cyclists out. You know the ones that appear for 50m then disappear into thin bitumen.

Maybe pointless and annoying but I don’t think you can blame the cyclists for it.

That’s not right. That’s not even wrong.

niftydog 11:02 am 07 Feb 12

What seems silly to me is that people are apparently happy to live 20m from a main road with no noise or visual barrier(s) between it and the front of their house.

re the hard left turns – I think it’s because of cycle lanes. Everywhere they install a new cycle lane they re-align the left turn slip lanes. Pointless and annoying if you ask me.

dvaey 10:59 am 07 Feb 12

OP: Oh one last thing why are all left turns at lights now being built with such hard lefts, whereas in the past they were a lot gentler?

In Kambah there are a number of instances of this. It is normally caused by having to make room for the on-road bike lanes. Pity it makes it significantly more unsafe for motorists, but at least the handful of cyclists who ride that on-road cycleway, now have one less thing to complain about.
