PortBUG: Dutch Roundabouts in South Australia.


New Dutch-style roundabout, Moray St, St Kilda, showing adjacent roadway crossings with green linking pathways.

Readers may have noted in a recent PortBUG post that DPTI were – until recently – considering the installation of a ‘Dutch-style’ roundabout at the junction of Hart and Carlisle streets as part of their redevelopment of Hart St, Semaphore. Unfortunately the new roundabout did not go ahead due to a lack of funding.

However two Dutch-style roundabouts are being built in St Kilda, Melbourne. This design separates cyclists from traffic and gives them the same status as pedestrians – which requires that cars give way to them where the bike-paths cross the entry roads. BISA was recently told that something similar has in fact been built by the Council in Mildura where separated paths allow cyclists to traverse each quadrant of the roundabout, separated from traffic.

It appears that the Mildura example caters for cyclists riding on the road and appears to lack the more prominent/raised pedestrian crossing which appears in the Saint Kilda (and presumably the Dutch) version. While it was disappointing that the Hart Street project did not go ahead, it’s been interesting to subsequently discover that DPTI have actually designed and built others, notably at Bolivar Road, Paralowie.

It appears that this new roundabout at Bolivar is linked to new off-road bike paths as well. Let’s hope that DPTI can keep experimenting with this design and start to retrofit the concept to exisiting roundabouts across the metro area as has been done in St Kilda!

    Yes, however the Bolivar Rd intersection isn’t connected to any othe infrastructure worth mentioning. It is an island in a sea of troubles.

    Thanks for the comment Ian. Our post was of course focussed on DPTI’s attempts and interest in this style of roundabout in SA. You’ve pointed out I guess and argued that the separations and protections offered by such a roundabout need to be ‘connected’ to ongoing or continuous separation if they are to be really worthwhile. I presume that you feel there’s a need for further separation on the roads that feed in to the roundabout – mainly Bolivar and Kings Road. Do either of these have bike lanes, paved shoulders or even off-road bike paths? Do you know what DPTI’s long-term plans are and what prompted their construction of this roundabout? Have you spoken to them at all about this? It would be interesting to follow this up with Minister Knoll’s office… maybe a project for the SalisburyBUG?
