The creation of a dedicated continuous lane from the Cotter Road onto Adelaide Avenue will shave up to five minutes off travel times into the city from Weston Creek and the growing Molonglo Valley, and help reduce accidents, according to the ACT Government.

But the move has upset the Greens, Woden Valley Community Council and Pedal Power ACT.

Minister for Roads and Active Travel Chris Steel said the work, to be done as part of the scheduled resealing program next week when traffic would not yet be at peak levels, was a natural extension of the Cotter Road duplication completed in 2017.

“The true benefits of the Cotter duplication won’t be seen until we make sure that we have a continuous lane on Adelaide Avenue for traffic coming from the Cotter Road so we’re not seeing traffic banked up in the morning coming east,” he said.

Under the changes, the Cotter Road on-ramp will continue on to Adelaide Avenue and become the left-hand lane. The T2/Bus Lane will be discontinued for a distance and will merge with regular traffic in the middle lane, providing three lanes of traffic city-bound.

The T2/Bus Lane will be reinstated on Adelaide Avenue when the road opens up to four lanes just north of Hopetoun Circuit. No changes are being made to the Southbound lanes on Adelaide Avenue.

But the Greens have questioned the decision take out a 1.3km section of the bus lane, saying it encourages more private car use and is out-of-step with the Government’s climate action commitments.

“We should be building more bus lanes, and giving more priority to public transport and car-pooling. That is what will make our city more sustainable and less congested in the long run,” Greens MLA Caroline Le Couteur said.

She said it should not be beyond the capabilities of the government to improve traffic flow without tearing up transit lanes.

Cotter Road On-ramp

The move has also upset the Woden Valley Community Council, which says it will increase bus travel times from Woden and Tuggeranong and is concerned about the impact on cyclists needing to cross to the cycling lane.

“Bus patronage from the south has already decreased by five per cent on weekdays since the introduction of Network 19 and the loss of the rapid service in the morning peak will also reduce the attractiveness of the service to the community,” it says.

Pedal Power ACT also says it has been flooded with calls from members and CEO Ian Ross says the new continuous lane will be much more difficult and dangerous to cross if vehicles are presumably now travelling even faster and not even looking out for other traffic as they won’t need to merge.

With the Cotter Road now carrying up to 25,000 vehicles a day, and traffic expected to grow to up to 35,000 cars by 2031 with the further development in the Molonglo Valley, the Government has been undertaking detailed traffic modelling on improvements to the road network on Adelaide Avenue and surrounding streets.

“Currently traffic from the Cotter Road has to merge with traffic on Adelaide Avenue, creating a bottleneck on both major roads,” Mr Steel said.

“The traffic modelling shows that the addition of a continuous lane on Adelaide Avenue from the Cotter Road on-ramp will improve traffic flow for Weston Creek and Molonglo commuters whilst not significantly affecting northbound traffic from Woden.”

Modelling shows commuters using Cotter Road will benefit from up to a five-minute reduction in their travel time during the morning peak periods, and commuters on Adelaide Avenue from Woden will only experience a five-second delay.

Mr Steel said bus users on the Cotter Road would also benefit from improved run times for Transport Canberra’s Rapid 7 and 10 services.

He said some motorists were also using Dudley Street to avoid merging with Adelaide Avenue from the Cotter Road and it was hoped the work would provide a better choice and reduce ‘rat-running’.

The $300,000 project will be delivered in two stages and involve resurfacing of the Adelaide Avenue stretch of road from Monday, 20 January. New line marking and signage will be installed, with the first stage expected to be completed before the start of the new school year in the first week of February 2020.

A second and final stage of works on Adelaide Avenue will be delivered a month later with final asphalt resurfacing and line marking.

Mr Steel also flagged other work in the area to improve traffic flows in and out of Yarralumla and Deakin, with new signallised intersections on Novar and Kent Streets.

Eventually, light rail stage 2 will occupy the median strip, freeing up the T2 lane for general traffic.

The greens virtue signalling is redundant. Bus usage has already been discouraged for southsiders when they screwed up the bus network. Many of us now have no choice but to drive. Why didn't the greens complain then?

Donna Scheerlinck Donna Scheerlinck 4:38 pm 17 Jan 20

What’s it going to cost all of us to save some of us 5 minutes?

Lyndon Zoukowski Lyndon Zoukowski 3:48 pm 17 Jan 20

Good idea

Max Robinson Max Robinson 2:17 pm 17 Jan 20

It’s about time the long suffering residents of weston creek had a descent run into town. The place has been there for 50 years or more and has only just got a dual carriage way. And stuff the greens and their nonsense. There is no public transport network in this town. You greens wanted light rail. The price of that was dismantling the bus network everywhere else. A bet le cooter drives a taxpayer funded vehicle wherever she goes

    Max Robinson I see Caroline regularly on the bus.

    Max Robinson Max Robinson 8:35 pm 17 Jan 20

    Richard Perry so she doesn’t get around in a government funded vehicle? It would be good if she used the bus. She would spend so

    Much time in transit that the damage done in the Legislative Assembly would be minimised

    Roderick Saunders Roderick Saunders 3:11 pm 19 Jan 20

    ACTION buses are mostly government-funded vehicles

I don’t cycle this route (Woden to Civic) anymore. Regardless of traffic density I’ve had too many close calls and one minor collision on this section. High speed traffic and complex road geometry does not facilitate safe cycling.

54-11 54-11 10:51 am 17 Jan 20

It just needs one cyclist to get in the way, and the whole lane will come to a screeching halt. This whole scheme will only work if the bike lanes are also removed.

David Jenkins David Jenkins 9:06 am 17 Jan 20

And yet the government is going to massively contribute to congestion in the vicinity in the future by its not building an integrated interchange to cater for the new Brickworks development when it's built...

Jenny Smits Jenny Smits 7:52 am 17 Jan 20

If they can’t also upgrade the bike crossing (or provide alternative fast bike path) then this will be a disaster for active travel. Agreed it is the worst for cars, but is also currently the worst for bikes, so scary to cross there - usually relies on a driver for letting you across rather than breaks in traffic. If there is another lane it will be impossible to get two drivers to coordinate letting a bike over. Mini overpass? Lights? Zebra crossing?

Andrew Lee Andrew Lee 12:30 am 17 Jan 20

Would be nice to get an access to Yarra Glen from Cotter Rd also...

    Craig Harrison Craig Harrison 8:37 am 17 Jan 20

    Andrew Lee yeah, everyone that lives in Coombes or Wright and works in Woden either has to deal with Hindmarsh avenue or sneak through Lyons causing chaos there. Multiple routes would definitely help this

Kazz Mac Kazz Mac 12:18 am 17 Jan 20

Why not use the parkway from Weston, it's heaps easier

    Jesse Mahoney Jesse Mahoney 10:20 am 17 Jan 20

    Kazz Mac because of the great bottleneck that is the big roundabout near the convention centre. It completly stuffs up parkes way, even for those turning into city West.

Richard Perry Richard Perry 10:11 pm 16 Jan 20

I commute by bike along Adelaide Ave. That intersection is sketchy enough with traffic from Cotter Road generally seeking to merge with traffic on Adelaide Avenue at a speed slow enough for mums, dads and others on bikes to negotiate. But giving Cotter Road traffic a dedicated lane that continues onto Adelaide will mean much faster moving cars at the juncture of Cotter and Adelaide. This will be deadly for vulnerable people on bikes. The government has already said it proposes no change to the current crossing for people riding bikes. As a major cycle thoroughfare, this is not okay!

Great band aid solution. Build some actual roadway instead of just changing some lines.

Fiona Dickson Fiona Dickson 8:35 pm 16 Jan 20

Why don’t they work on public transport connectivity instead? This is a city making all the same missteps that congested cities wish they could undo. Come on ACT government - where are your push pull traffic management strategies?

    Graham Franklin-Browne Graham Franklin-Browne 9:00 pm 16 Jan 20

    Fiona Dickson Agree. According to the mantra "build more roads and they will come...and the roads will be full again"

    Fiona Dickson Fiona Dickson 9:12 pm 16 Jan 20

    Graham Franklin-Browne yes - crazy short sighted

    Paul Leins Paul Leins 9:39 pm 16 Jan 20

    What if I told you they're doing more than one thing at a time?

    Julian Clarke Julian Clarke 10:25 pm 16 Jan 20

    From a city that has only just completed a tram service from the outer suburbs to the centre? There was a lot of protest over that too.

    Fiona Dickson Fiona Dickson 7:27 am 17 Jan 20

    Julian Clarke yes they’re doing left hand versus right hand, uncoordinated and cancelling out efforts. Major cities dealing with congestion would never increase roads as a solution to reduce congestion. Singapore, London, Portland and a bunch of other cities provide good examples of what not to do and what to do. They’ve been there and done that and seen how increasing roads fails and just increases traffic. If you’re going to invest in public transport do it properly and wholeheartedly not this pissant approach the ACT government has taken. Put in a tram, cut bus services and increase road lanes. It’s beyond pathetic that our planners can’t get this right given the multitude of lessons in traffic management from around the world. But hey, who wants to get in the way of an infrastructure project. This government’s main purpose is keeping the construction industry happy.

    Fiona Dickson Fiona Dickson 11:05 am 17 Jan 20

    Gwg Heldon yup totally agree.

    Fiona Dickson Fiona Dickson 1:09 pm 17 Jan 20

    James Dof yup I’m with you on that. And then could change to trackless light rail when it’s ready. Would have been the smarter solution.

    Fiona Dickson Fiona Dickson 2:16 pm 17 Jan 20

    James Dof yup they’ve done exactly the opposite of what is needed to make a public transport system work - instead of making it more convenient they’ve made it less - simpleton short term-ist cost cutting instead of investing to shift the transport culture and make it a viable system over the long term.

Jesse Mahoney Jesse Mahoney 7:28 pm 16 Jan 20

That T2 lane is great for those of us who carpool. This is just introducing a short, yet frustrating, bottleneck for those who actively seek to not be single person cars.

Kim KD Winks Kim KD Winks 6:51 pm 16 Jan 20

Why don’t they work on the bottleneck of Johnson Drive and Monaro Highway.....it’s ridiculous and dangerous.

    Ashley Wright Ashley Wright 6:56 pm 16 Jan 20

    Kim KD Winks probably a bit harder than what they are planning here. This is just line marking.

    Kim KD Winks Kim KD Winks 6:58 pm 16 Jan 20

    Ashley Wright true but better planning in the first place shouldn’t have let it happen. The bottleneck on the highway has been bad for years. 😀

grim123 grim123 3:07 pm 16 Jan 20

So it doesn’t fix the thing slowing up the whole cotter road in the first place, which is the merging (or, peoples inability to merge) right after the lights, that is shown from 00:28 in the video?

Fail.
