Ask Phoebe: What are two or more major transportation projects like?

I would like to see the graphs of the two major transportation projects on offer: the Puhoi-Wellsford Expressway and the CBD railway line. I understand that the road has been announced but I have not seen a map of the road. And although there are 2D displays of the downtown Britomart railway loop at Mt Eden, I have not seen the vertical look. A tunnel is mentioned, but the line should surely cross SH1 to Spaghetti Junction, above the highway. Could you show pictures of both or indicate a web link that does?
John Paynter, Auckland.

I am happy to help. The Puhoi-Wellsford Highway graph is for illustrative purposes only.

This could still change with the environmental and technical imperatives. You can find out more about the project at

.

The CBD underground railway is the preferred option at this stage. It is a tunnel with a total length of 3.5 km. It will be deep enough to protect existing structures, including building foundations and highway foundations. I'm afraid I do not have a 3D image, but you can read more about it on

and go to the CBD rail link.

Both projects were widely covered in the Herald, most recently last month.

Why do the two green lights come on at the same time on the highway ramps? If the lights alternated, some of the dangerous race starts could be eliminated and traffic on the highway would be smoother and safer. What do I miss?
Brian Chippindale, Silverdale.

The Transport Agency tells me that in the United States and some European countries, green lights work alternately in each lane. The introduction of this system here would seem to require a change in the law, although it is unclear why this would be a deterrent when other laws could be enacted at the time. hurry.

Another option, to shift the onramp stop line so that vehicles do not leave together, has been tested here, but has no advantage in terms of traffic flow to the freeway.

In the afternoon, I regularly go to Cavendish Drive, Manukau, and wonder if the cars stop in the bike lane while waiting to turn left. The same question applies to cars coming out of traffic lanes – can they stop along the bike path while waiting for a hole in traffic to stop?
Phil Christopherson, Pakuranga.

Cars can take a bike path to get to their destination, but they can not linger there. The use of vehicle lanes should be minimized by other vehicles. If a driver has to wait to turn left or right, he has to wait outside the bike lane. When crossing a bike lane or other vehicle lane, motorists must give way to the traffic authorized to use the lane.
