Time: Anytime from 7:45 to around 8:45 weekdays (and around 15 seconds from the above).
Cars turn left into the merge lane and (hopefully) accelerate to 80kph to merge into left hand lane of the Barton Highway.
What happens? (and far too often?)
All the cars coming from the Barton Highway/Clarrie Hermes Drive traffic lights have to start slowing down for the speed camera (having raced off from the lights).
One car coming out of Curran Drive stops in the merge lane – either where the lane ends, in which case one or two cars may stop behind it before those at the back pull out directly into the Highway (yes, these are usually utes, or 4WDs, or both) – or on the corner where the lane begins!
Either way, this is danger central.
So while the lights help those coming out of Clarrie Hermes and Kuringa, they have helped make the Curran Drive intersection more of a death trap.
This could easily be mitigated by extending the southbound merge lane. Or by having built a proper road in the first place.
As for trying to turn right out of Curran Drive into the Highway at go home time, that’s another story. And of course those heading north are all accelerating in both the left and right lanes, having just negotiated the other speed camera.
