When current roads minister, Duncan Gay announced the start of construction work of WestConnex, a major motorway project for Sydney i was not sure if I was excited or disconcert. For someone getting excited over a road sounded more like a mental condition there’s a bit more to the background of my initial expression. Currently, the car is part of my job description which I use daily with most trips involving funneling through the disaster that is the M5 East, a road tunnel that plays an important role in Sydney’s orbital motorway but was built without any future proofing that has a repetition for it’s bad and worsening traffic so it was no surprise to me personally that an improved M5 would sound like a god send. However, questions were begged over the overall outcome of the project and how it would evolve from the initial announcement into reality and the more the details, environment reports and plans came forward the more the project became twisted and fraudulent.
“They will be rejoicing, they will be singing in their cars, frankly, because their cars will be moving,” – former Prime Minster Tony Abbott, Sydney Morning Herald March 8th 2015
“The previous Labor government had 16 years to do something about the missing
links but squibbed every opportunity. While separate investigations have been carried
out for major projects on the M4 and M5 in the past, this is the first time the corridor
has been looked at in its entirety. – former NSW Premier Barry O’Farrell, Media Release 3rd October 2012
WestConnex is being put forward as the most ‘important transport infrastructure project’ in Sydney. The billions of federal and state funding being pumped into what most see and hope will be the golden paved road to fix the major bottlenecks of the motorway network and it’s no surprise the project has it’s supporters due to the lost productivity and economic losses that comes out of congestion. But even still, building motorways is nothing new and past attempts to address congestion have resorted to just short term benefits or causing further problems down the track.

It is no surprise that the old nature of building roads to address congestion is faltering with more active mass transit solutions being put to the table. However, the lack of political will to prioritise public transport is still a large concern due to a heavily dominated roads lobby, disappointment of previous major transport projects resulting in projects being finished overdue and over budget such as the problems associated with the Epping to Chatswood Rail Link and a heavy car dependent population ranging into the 70-80% of total trips travelled in most major cities.
“The U.S. government is also in the business of providing people with a good they really want: roads. And just like the old Soviets, Uncle Sam is giving this commodity away for next to nothing. Is the solution then to privatize all roads? Not unless you’re living in some libertarian fantasyland.” – What’s Up With That: Building Bigger Roads Actually Makes Traffic Worse – Wired, 2014
Westconnex has been the result or more-so like a Frankenstein of 30 plus years of road planning, cancellation and mishaps. Since as early as the 1950s, the original corridor for the Western Expressway proposed the highway starting in the inner west around Glebe and Five Dock. When the M4 as we know it today was constructed during the 60s and 70s, heavy opposition and a mood of change against vast motorway planning and viaducts during the Wran Government prevented any extension of the motorway past the ‘temporary’ end at Concord with the section canned in Feb 1977 and the corridor sold. If built during the 1970s, the extension would have cost $287 million (not adjusted from inflation) but the nature of the inner west would look very different to the present day.

Following the years after the cancellation, Parramatta Road become worse overtime with the growing population that resulted with the Department of Main Roads drawing up new plans to complete the M4. To avoid the nightmare of the viaduct, the preferred option was to sink it with various options proposed including a slot option. With the Sydney Olympics fast approaching, the plans became fast tracked during the Carr Government which promised construction of the new dubbed ‘M4 East’ by the new millennium as part of Action for Public Transport 1998. The M4 East would form part of the 2-lane City West Link, a cheaper but more negotiable option instead of a elevated freeway.

While the Olympics came and went, the project was already heading in disarray. No work had began on the M4 East instead of some study options proposed in 2002 and the City West Link became increasingly congested due to a lack of grade separation, traffic intersections and future proofing. With no hope of starting construction on the M4 East and growing concerns about if the City West Link including as well if the ANAZC Bridge (which also reached peak capacity) will cope, the project was dumped.
A significant amount of traffic leaves Parramatta Road at Haberfield and uses the City West Link and Anzac Bridge to access the CBD and Sydney Harbour Bridge. A significant amount of traffic also leaves Parramatta Road at/near Lewisham and travels through or near Marrickville to locations such as Sydney Airport, Port Botany and the SSGC. – RTA M4 East Tunnel Option Study (2002)
Today, the new ‘M4 East’ is being constructed as part of WestConnex but the initial concept of what was the original proposal; connecting the western suburbs to the CBD mysteriously changed following the 2014 Budget when a new Northern Extension was added onto the project. The tunnel still connects to the City West Link and ANZAC Bridge which has congestion much worse then 10 years ago but the major scope of the M4 East now concerns the Northern Beaches rather then the CBD.

Northern Extension also known as WestConnex Stage 4 – Westconnex Site
While the WestConnex site has no mention of this, Infrastructure Australia proposes WestConnex Stage 4 as a top priority creating another CBD bypass and hence moving the original M4 East route away from Parramatta Road and instead to Balmain, which angered some prominent people who supported the project including former Prime Minister Paul Keating. Was this change due to a heavy Liberal Party presence north of the bridge to bring in North Sydney as part of the WestConnex project? Personally, I can’t make that call.
Despite the route diversion, the M4 East also faces criticism about the tunnel itself, the spaghetti intersections at Concord and development interests concerning Parramatta Road and the former rail lines near White Bay Power Station. For example looking back at the Lane Cove Tunnel built in 2007, Epping Road was reduced from 3 lanes to just one forcing users into the tunnel with one lane converted to a 24 hour bus lanes that carries buses on a poor frequency not fulling the standards of a bus rapid transit. There is no doubt Parramatta Road will face the same fate if the bus or light rail service proposed is not sufficient and that drivers will be diverted or even forced to use the tunnel.

The current Lane Cove Tunnel
The M4 will also be re-tolled which is also poorly mentioned on the official sites, media releases, even on the overpass ads themselves. Nobody knows what the tolls will be, if they are kilometer based or a flat fare (while they are saying WestConnex will be kilometer based, no official announcement has been made) and how long they will be in place. Some drivers didn’t even know the M4 was to be tolled again until they saw the toll booths, not so much a particular friendly sight.
Back to the 90s and while the Carr Government initially screwed up the City West Link there was also the missing corridor between South-West Sydney and Sydney Airport. To avoid the same mistake, the M5 East tunnel was constructed on time opening in 2001 with the major difference being built by the former RTA and not being built as a PPP (Public-Private Partnership) . This meant the tunnel opened and still is (for now) toll-free. But even with the toll-free tunnel, the project came under heavy criticism of its planning, construction and environmental concerns.
“The M5 East project is one I am very proud of, which has made a huge difference to the quality of life for thousands of families in the southern and south-western suburbs of Sydney,” he said. – Former Road Minister Carl Scully, September 9 2003
The first-for most issue with the tunnel is the construction and how poorly it addresses the corridor. Without going too much into detail, the tunnel was too steep, had not enough lanes and was too low making it one of Sydney’s most congestion motorways every day of the week. Why nobody at tender stages saw these issues and took on the additional funding to address these design changes before construction was primly for mere personal merit. The congestion also played a role in changing the merits of how people travelled with less people catching adjacent public transport and people or trucks getting stuck in the tunnel on a common basis.
Stage 2 of WestConnex is being put forward as a band-aid to address the congestion issues of the M5 East. The tunnel is higher, the gradients are narrower and the tunnel is three lanes but this tunnel has its own problems. Initially, the WestConnex proposal was to upgrade the existing tunnel or to parallel with the current one but the tunnel goes on an entirely new direction with the first exit at St Peters being further from the International Terminal and Port Botany. Despite the efforts of getting people to use the new M5 such as yet to be released way-finding signage, most drivers could end up using the existing tunnel simply due to the quicker direction. In addition, the tunnels new and old will both be tolled with little to none information similar to Stage 1.

St Peters Interchange – WestConnex site
WestConnex Stage 3 has been one of the most decisive arguments about the project as a whole. In general, the link is aiming to address the most slowest corridor in Sydney, the Princess Hwy which can average a speed of 14km/hr in peak according to the RMS. The link has also come under question by both the NSW Labor who as part of their 2015 Election campaign promoting scrapping Stage 3 (they supported Stage 1 and 2 with revised business cases) and transport experts have questioned the traffic forecasts of the link with no clear indication of how many vehicles will use it per hour while keeping in mind forecasts have been wrong in the past such as forecasts for the Lane Cove and Cross City Tunnels.
“The community can have no confidence in WestConnex until the business case is publicly released and the route doesn’t dump hundreds of thousands of cars and truck in the middle of St Peters,” – Shadow Minister for Roads Michael Daley
The link will also have a entry point near the University of Sydney to try and pressure people away from the ANZAC Bridge which was also proposed by former Prime Minister Julia Gillard’s proposal of linking WestConnex to the CBD. However the former Federal government had more skepticism over the current WestConnex scope that the previous Abbott government. Should the Rudd government won the near impossible 2013 election, the entire nature of the project could be much different than what is being constructed today.
“We want the State Government to come up with a real plan for western Sydney that ticks those boxes and we obviously want that to happen sooner rather than later.” – David Bradbury – Labor MP

Boston Big Dig – before and after – Wikipedia
WestConnex has quite a bit of uniqueness of what it is trying to fix all in one go though the reality will be the project will only fix congestion temporary unless the car dependency of Sydney dramatically drops. But WestConnex is not the only project of this kind with one in the US with similarities. Over in Boston, there is still questions of the legacy of the “Boston Big Dig” (Central Artery/Tunnel Project), dubbed the most expensive freeway project in recent United States history. Like the WestConnex, the Big Dig project was designed to address congestion leading into Downtown bit like the congestion leading to the Eastern Distributor in which Stage 3 is addressing. Without going into too much detail the Big Dig was a disaster before and during construction with costs overblown, delays, redesigns and overall an engineering nightmare. Today, Boston is still paying off its major motorway project until 2038 with little to none of the promised mass transit projects part of the Big Dig scope being built. While it was not all doom and gloom, the Big Dig did clean up the spaghetti motorway network in Boston at the time while opening up space for recreational use.
But did it solve the congestion problem? A bit of yes and no.
Firstly, yes it did. The congestion did decrease with the additional capacity of a second north-south tunnel. According to the Massachusetts Department of Transportation, significant travel times were reduced on the Interstate I93 and around the Boston Airport.
Due to traffic improvements and substantial reductions in traffic delay, the total vehicle- hours of travel on Project highways has dropped 62 percent between 1995 and 2003 and are now providing approximately $168 million annually in time and cost savings to travelers. Residents from south and west of Boston average travel times from the I-90/I-93 interchange to Logan Airport during peak periods have decreased between 42 and 74 percent depending on direction and time of day. In 2004-2005, the “savings for travelers was estimated at $166 million annually” – Link
However, while it did reduce some choke points here and there. The golden rule of any massive transport infrastructure megaproject is always the same; “Build it and they will come.” And so in 2008, traffic began to spread into more outward areas causing little to no improvements to travel time as mentioned.
Today’s marquee mega projects are all about mass transit. Should so much have been invested in new highways? A little-known fact is that there was another way. Confronted by the deteriorating Central Artery back in the 1980s, we could have chosen not to replace it at all. – 10 years later, did the Big Dig deliver? – The Boston Globe
There is no doubt WestConnex will benefit many (myself included) but major road motorway projects like this may could be coming to a end. There is growing sediment particularly in recent years of billion-dollar motorway projects (such as the East West Link) and the few long term benefits they provide while causing more congestion then they reduce. It’s pretty sad that people today still believe the buzzwords of a motorway to fix congestion where the evidence is clearly out that these projects do not benefit in the long run. The WestConnex fills like a guilty pleasure, a gamble if you like where the odds will never be in your favour and you can never win back on the losses but you still get a guilty joy of doing it anyways.
