Transurban Unlocks 30,000 Daily Trips on M7 as A25 Sale Frees $280M for US Growth
Transurban Group has completed a major capacity expansion on Sydney’s M7 Motorway whilst simultaneously monetising a non-core Canadian asset, according to an update released 15 June 2026. The M7-M12 Integration Project delivered an additional lane in each direction across 26 kilometres, with the interchange opening to traffic 14 June 2026 following completion of the widening component on 8 May 2026. Separately, Transurban entered an agreement with La Caisse to sell its remaining 50% interest in Montreal’s A25 concession for CAD 280 million, with proceeds targeted to support North American growth initiatives. Group traffic increased 0.1% in May versus the prior corresponding period, reflecting mixed regional performance across the portfolio.
M7-M12 Integration Project delivers 30,000 additional vehicle capacity
The completed project is expected to increase the M7 Motorway’s capacity by up to 30,000 vehicles per day, according to the company’s traffic and transport assessment. The widening spans from the M5 Motorway at Prestons to Richmond Road at Oakhurst/Glendenning, whilst the newly constructed M7-M12 interchange provides connection between Elizabeth Drive and the M12 Motorway. The project is also expected to support connection to the new Western Sydney (Nancy-Bird Walton) Airport.
The Westlink M7 refinancing completed in May 2026 secured a A$300 million syndicated bank facility through to April 2029, removing near-term rollover risk on the same corridor now benefiting from the capacity expansion.
Travel time improvements are material. A typical peak-hour trip between Marsden Park and Liverpool is now up to 13 minutes faster, with total time savings of up to 27 minutes when compared to non-tolled alternatives, based on TomTom data and internal analysis for the PM peak southbound period (4-5pm) comparing May 2025 pre-widening conditions to May 2026 post-completion.
Michelle Jablko, CEO
“We have delivered 26 kilometres of widened M7, making a typical peak-hour trip between Marsden Park and Liverpool up to 13 minutes faster and saving customers a total of up to 27 minutes when compared to the non-tolled alternative.”
The widening and interchange are expected to support future development growth in Western Sydney through improved travel times and reduced congestion. The project connects to the new Western Sydney (Nancy-Bird Walton) Airport, supporting the region’s long-term traffic demand.

What is toll road capacity expansion and why does it matter?
Toll road widening increases the number of vehicles that can use the motorway during peak periods, directly enhancing revenue potential without requiring the acquisition of new concessions. When a toll road approaches capacity, congestion reduces throughput and degrades the customer experience. Adding lanes alleviates bottlenecks, allowing more vehicles to travel at higher speeds whilst maintaining toll collections per trip.
For Transurban, the M7 widening represents low-risk revenue growth on an existing asset with established traffic patterns and inflation-linked pricing mechanisms. The connection to Western Sydney Airport provides a long-term structural traffic driver, as the airport is expected to generate significant commercial and passenger vehicle movements when operational.
For income-focused investors, capacity expansions on existing concessions offer predictable revenue uplifts without the regulatory approval timelines or development risks associated with greenfield projects.
A25 sale recycles capital into US growth corridor
Transurban entered an agreement with La Caisse for the sale of its remaining 50% interest in the A25 concession in Montreal, effected via the sale of Transurban’s indirect interest in Concession A25 Limited Partnership. Financial close is targeted by the end of June 2026.
The company is expected to receive total consideration of CAD 280 million, which is broadly consistent with both the 50% sale completed in March 2023 (adjusted for distributions) and the current carrying value of the asset. Proceeds from the transaction are expected to support other North America growth initiatives including in the Greater Washington Area. Transurban’s A25 staff will transition to La Caisse with the sale.
| Transaction Detail | Value |
|---|---|
| Asset | A25 concession, Montreal |
| Stake sold | 50% (remaining interest) |
| Consideration | CAD 280 million |
| Buyer | La Caisse |
| Expected close | End of June 2026 |
The sale at carrying value validates Transurban’s asset valuations whilst freeing capital for higher-growth US express lane opportunities in the Greater Washington Area. The transaction demonstrates active portfolio management, with the company exiting a mature Canadian asset to redeploy capital into markets offering superior toll pricing dynamics and traffic growth.
May traffic shows regional divergence across Australian and US assets
Group traffic increased 0.1% in May versus the prior corresponding period, consistent with the 0.6% growth recorded in April. Regional performance diverged materially across the portfolio.
Australian markets:
- Sydney: Traffic increased 0.1% as construction activity from the M7-M12 Interchange abated
- Melbourne: Traffic grew 1.7%, including the contribution from the West Gate Tunnel project
- Brisbane: Traffic decreased 3.2%, largely due to weather impacts (rainfall for the month was approximately four times that of May 2025)
Commercial vehicle traffic in May increased 4.0% across Australian markets, with the figure at -2.0% excluding West Gate Tunnel.
Greater Washington Area performance:
- April: Traffic grew 7.5%
- May: Traffic grew 2.4%
Dynamic toll pricing growth remained robust in May, with average tolls rising 4.7% on the 95 Express Lanes and 32.0% on the 495 Express Lanes. The customer value proposition from Transurban’s express lane network continues to support ongoing price growth.
As highlighted in Transurban’s ASX release on 4 May 2026, the West Gate Tunnel ramp-up continues to be influenced by the macroeconomic environment, with traffic growth remaining consistent with April. The company will continue to monitor the impact of the current geopolitical and macroeconomic environment, noting that the duration and extent of any impacts will depend on geopolitical developments in key energy producing regions, government policy decisions and the broader macroeconomic response.
The regional divergence highlights portfolio diversification benefits. Strong US express lane pricing offsets weather-affected Brisbane volumes, whilst Melbourne’s West Gate Tunnel ramp-up adds incremental revenue.
Inflation-linked revenue provides defensive positioning
More than 90% of Group revenue is CPI-linked or subject to fixed escalators, with inflation impacts typically flowing through over a period of up to 18 months. The resilience of the portfolio is underpinned by the essential nature of the Group’s urban transport assets.
Transurban continues to actively navigate the current macroeconomic and geopolitical environment through disciplined balance sheet management, operational focus and a continued commitment to delivering value for customers. The inflation-linked toll structure provides natural revenue protection, supporting distribution sustainability through economic cycles.
The WestConnex bond issuance priced in April 2026 raised A$1.21 billion in senior secured notes ring-fenced at the asset level, a structure that leaves Transurban Group’s own balance sheet unaffected while extending the debt maturity profile across 2032 and 2036.
The company acknowledged it will continue to monitor geopolitical and macroeconomic developments, whilst noting that the West Gate Tunnel ramp-up continues to be influenced by the macroeconomic environment per its 4 May 2026 ASX release.

Near-term catalysts and outlook
Upcoming events for investors to monitor include:
- A25 sale financial close: Targeted by end of June 2026
- West Gate Tunnel ramp-up: Ongoing monitoring of traffic growth and macroeconomic influences
- Greater Washington Area growth initiatives: Capital redeployment following A25 proceeds receipt
Transurban continues to monitor geopolitical and macroeconomic impacts, with the duration and extent of any effects dependent on geopolitical developments in key energy producing regions, government policy decisions and the broader macroeconomic response.
The A25 close provides near-term capital clarity whilst the M7 capacity upgrade positions the company for Western Sydney’s long-term growth tailwind as the region’s population expands and the new airport drives incremental traffic demand.
