Why have the concrete islands at the new traffic lights in Holt been installed in a manner that forces all traffic heading East on Southern Cross Drive to merge down to one lane before those cars wanting to turn left into Florey Drive can exit into the very short slip lane?
Why did they not keep the longer slip lane, facilitating better traffic flow for those cars turning left into Florey Drive?
To my mind, the following implications apply:
- — No-one will be able to turn right out of Starke Street at peak times. Traffic will be backed up past the Starke Street/Southern Cross Intersection when the lights are red.
— No-one will be able to turn right out of Beaurepaire Crescent at peak times. Drivers trying to avoid the traffic jam at the new traffic lights will turn up Beaurepaire Crescent creating a constant line-up of cars turning off Southern Cross Drive. When really busy, traffic will possibly be backed up past this intersection as well when the lights are red.

— Once the back-log of east-bound cars are cleared, drivers waiting to turn right out of Starke Street and Beaurepaire Crescent will then have to wait for the west bound traffic to pass that has just been given the green light.
The EIS into the first stage of New Macgregor showed an increase in traffic on Spofforth Street from 1200 to 5200 vehicles a day. Now that the 13 speed bumps have been installed on Spofforth Street, most of these vehicles (which probably number even more now that Stages 2 and 3 have been completed) are all travelling down Southern Cross Drive. That’s a lot of cars travelling through the new bottle neck each day.
