Was West Gate Tunnel Worth Building?

Overall takeaway

The video argues that the Westgate Tunnel should be judged on two separate questions—whether the infrastructure is good and whether the deal was good—and concludes:

• Road quality: mostly yes
• Deal for the public: mostly no

---

What was built / why it exists

The project created roughly 8 km of new toll freeway, including:

• twin tunnels under Yarraville
• a new Maribyrnong River bridge
• an elevated section over Footscray Road, connecting into CityLink and the port

It also widened the Westgate Freeway further west.

The core purpose is to give Melbourne’s west a second river crossing, reducing dependence on the Westgate Bridge.

The strongest pro-tunnel case: redundancy for the Westgate Bridge

The speaker emphasizes that the Westgate Bridge (opened in 1978) has grown from about 40,000 vehicles/day to ~200,000, and that it carries a major freight corridor.

Even though it has been strengthened (notably with ~$70m in recent works), the speaker argues that:

• maintenance demands will only increase
• closures would squeeze the whole west because there was previously no effective alternative route

The new tunnel/route is presented as providing that backup capacity.

Freight and local impacts

A key benefit claimed by the government is that the tunnel will remove trucks from residential streets in Yarraville and Footscray.

• The video cites a projected shift of about 9,000 trucks/day
• It also notes the speaker wants actual traffic counts, rather than relying on press-release figures

---

Timing argument: benefits may be underestimated in “spreadsheet” analysis

The video claims conventional benefit-cost methods:

• discount future benefits too heavily
• struggle to value redundancy, meaning the project can look worse “on paper” than it might in real long-term planning

It also argues that the tunnel appears “quiet,” and cautions that toll roads take 3–5 years to fill, citing examples like Eastlink—drivers stick with what they know until habits and surrounding development catch up.

The “dead-looking” tunnel early on is framed as potentially a good sign of spare capacity.

Why the deal is considered mostly bad (money side)

While acknowledging the headline cost blowout, the speaker challenges the claim that all taxpayers funded a wasted $10b.

• Total cost: ~$10.2b
• Taxpayer-funded portion from the state budget: ~$4b
• The remaining funding is carried by Transurban, repaid via tolls until around 2045

When costs rose after a contaminated soil dispute, the added burden was split (reported as):

• Transurban: ~+$2.2b
• Builders: waived ~$1b
• Government: added ~+$1.9b

The speaker describes this as a “pain-share contract” dynamic.

The main disappointment: tolling CityLink to benefit Transurban

The central critique is not the ~$4b public contribution itself, but that to make Transurban’s arrangement work, the government extended Transurban’s right to toll CityLink until 2045.

The video cites independent analysis suggesting ~70% of the extra toll revenue would come from CityLink drivers, not from people using the new Westgate Tunnel.

The speaker argues this means a large portion of the taxpayer-adjacent protection is ultimately paid by people who never use the tunnel, via higher CityLink tolls over the next two decades—creating an outcome where the cost is “quietly” shifted.

---

Conclusion / forecast

The speaker predicts that in 20–30 years, the tunnel will likely look like the right decision, mainly because of:

• the value of redundancy for the Westgate Bridge
• credible freight benefits

However, the speaker emphasizes that the tunnel’s performance won’t be truly validated until real traffic data is available.

They encourage viewers to share whether it saved the promised ~20 minutes.
