Congestion is the issue. In this case on the Great Western Highway

Congestion is part of life these days (and has been for quite a while). It will always be with us and we have to learn best how to manage it.

Congestion slows traffic. It delays both people and freight between the Central West / Orana and the Sydney Basin (including both Newcastle and Woollongong).

Time is money especially for business.

Time is also valuable for leisure travellers.

You cannot build your way out of road congestion: you can only move it from one place to another, or worse still add to it.

Flashback to 1965 (Youtube): there was road congestion even then. It will always be with us unless we change our thinking

What is wrong with the idea of duplicating the highway?

We could build an underground dual road carriageway from Hartley to Lapstone. That would only cost somewhere between $40 and $50 billion! That is what we would call a boondoggle. But we are concerned about a road not the Sydney Opera House.

This site will look at how best to ease congestion, with a specific focus on the Lithgow to Katoomba corridor.

It boils down to this: if you have parallel road and rail corridors and want to reduce road congestion you invest in the rail line, not the road. 

Rail is the most cost effective and safest way of reducing congestion.

For the GWH, in the short term, putting trucks on trains is an incremental and affordable way of easing congestion on the GWH. It is usually called a "Rolling Highway" - for detail about this please navigate using the bars at the left (top left if on a phone or tablet) or go straight to the Rolling Highway page here.

It is a drive on and off system: There would be terminals near Lithgow (Marangaroo?) and St Marys / Rooty Hill. It would use the existing rail system and requires significantly less expenditure than a road solution.

Advantages

Issues to be addressed

The video below shows the rolling highway over the Brenner Pass (between Austria and Italy). It is very similar to the line over the Blue Mountains (ie. has the same gradient).

For detailed information on the rolling highway go to this page (this site).

In the long term, investment in intermodal rail facilities and increasing the number of people who choose to use the train,  on all 3 routes between the Central West and the Sydney Basin, is the solution.

Extract from "Future Transport 2056"

Roads through and around these centres ... serve a place function by operating in a way that allows attractive places for people and strong local economies to develop and thrive. p.17

The NSW Government will work with local councils and communities ... to develop 20 year precinct plans for all strategically important centres and places. The plans will focus on balancing the transport movement needs of the community with high quality urban design that supports community safety, health and wellbeing and enhances community assets and local character.   p.20

"In markets with lower contestability, such as some areas in regional NSW and customer segments where disadvantage exists, we will need to look to more innovative procurement practices, where services that better respond to customer needs, and deliver better value for money for government, are purchased." (emphasis added) p.76

Comment: Exactly. We need new thinking, meeting needs and cost effectiveness
