Transurban recorded 3.4% growth in Group average daily traffic in August, with North America again providing the standout performance. The result was positive overall, although Melbourne’s underlying traffic fell once the West Gate Tunnel contribution was removed.
- 3.4% Group average daily traffic growth in August
- North American traffic increased 12.3%
- M7 traffic climbed 11.8% in Sydney
- Melbourne traffic fell 0.8% excluding West Gate Tunnel
- More than 90% of revenue is CPI-linked or escalated
North American lanes lead August traffic growth
Transurban Group (ASX:TCL) delivered 3.4% growth in average daily traffic in August compared with the prior corresponding period, but the headline number understates the sharpest part of the portfolio. North American traffic rose 12.3%, led by a 26.1% increase on the 495 Express Lanes and 3.8% growth on the 95 Express Lanes.
The 495 Express Lanes also recorded a 36.0% increase in average dynamic toll prices, while prices on the 95 Express Lanes rose 5.8%. Transurban attributed the movements to additional capacity from the recently opened 495 Northern Extension and the value customers place on its Express Lanes. The figures combine traffic and pricing momentum, although the announcement does not translate either measure into an earnings forecast.
North American traffic figures for July and August relate only to the 95 and 495 Express Lanes after the A25 divestment reached financial close on 15 June. Earlier percentages have been adjusted to exclude A25, improving comparability across the reported series.
Sydney gains from M7-M12 integration
Sydney traffic increased 3.3%, supported by continued growth on the M7. Average daily traffic on that road rose 11.8% following the opening of the M7-M12 Integration Project, making it the clearest Australian growth pocket in the August release.
Melbourne traffic grew 3.5% overall, but that result was heavily influenced by the West Gate Tunnel. Excluding WGT, Melbourne traffic declined 0.8%. The same adjustment reduced Group traffic growth to 1.9%, a useful reminder that the reported 3.4% figure includes the contribution of a recently opened asset rather than representing uniform growth across the network.
Brisbane was comparatively subdued, with traffic up 1.0%, although large vehicle traffic increased 3.7%. Transurban said more than 90% of Group revenue is CPI-linked or subject to fixed escalators, with inflation impacts typically flowing through over as much as 18 months. That feature provides a degree of revenue protection, but the company also flagged renewed conflict in energy-producing regions and wider macroeconomic and geopolitical conditions as ongoing watchpoints.
Traffic figures may be revised as trip processing is completed, and Transurban plans to continue releasing monthly data for the remainder of 2026. The next releases will help establish whether North America’s double-digit growth and Sydney’s M7 uplift are durable trends, or whether August benefited from unusually favourable comparisons and newly added capacity.
Bottom Line?
The portfolio remains operationally resilient, but the quality of growth now depends on whether North American momentum persists and how much Australian performance relies on West Gate Tunnel effects.
Questions in the middle?
- Can North American traffic growth remain in double digits as the new capacity matures?
- Will Melbourne return to underlying growth once West Gate Tunnel comparisons normalise?
- How much of the traffic and dynamic pricing uplift will flow through to revenue over the next 18 months?
