Coomera Connector, Australia.

[Peter Freeman]

This motorway project has been mentioned already (p8 of 'Australian Motorways' topic in 'International Roads' forum), but I'm starting this topic as somewhere to record its progress over the next few years.

Gold Coast is a major and growing city 100km south of Brisbane, to which it is connected by the M1 Pacific Motorway. M1 continues north and south along the east coast, but is congested where it passes close by Gold Coast because its strategic traffic is supplemented by local commuters. Coomera Connector's purpose is to relieve M1 of this local traffic. Construction will be staged: Stage 1 (consisting of north, central and south packages) and Stage 2. Stage 1 north has begun.

To start, here are some links.

A bit disappointing to see the junctions are plain diamonds with left filter lanes. I would have expected SPUI or DDI these days.

A bit disappointing, yes, especially in Queensland, Australia's most progressive state for interchange innovation. However, AU is still in the 'pilot' phase for its DDI's: three in operation, one under construction, three planned. Our default is still the diamond. This might still be the case in USA too (with exceptions MO and KS), despite USA now having >80 operational DDI's.

SPUIs are well-established here though: Sydney has about 20, Melbourne soon 9. Coomera Connector may yet have some detail design to finalise, so I wouldn't be surprised if a SPUI turned up somewhere along there.
