Auckland exploding population causing grid lock at SH1 to16 junction

Clive from Green Bay

With all the improvements on the SH1 the traffic should be flowing properly by now but the increase in traffic due to growing population has overtaken the benefit of road widening.
It would be wonderful if population had remained static with no new buildings for last few years, but by keeping on building houses and infrastructure which causes global warming nothing has changed.
So should we
1. Introduce Congestion charges/tolls to limit traffic at rush hours.
2. Fine people with only one person inside a car in rush hours.
3. Level off a cycle path beside suburban railway lines
4. Reduce local bus fares to $1 for each bus entered. $3 for express.
5. Reduce population growth thus stop the need to build which will lead to a higher standard of living for us all.
