WestConnex M8

The WestConnex M8 connects Kingsgrove to St Peters via new nine kilometre twin tunnels, reducing congestion and halving travel times on the M5 East motorway. The M8 runs from the King Georges Road Interchange at Beverly Hills to a new interchange at St Peters (built on the former Alexandria landfill site). The St Peters Interchange connects to the local road network through Euston Road, Campbell Road and Gardeners Road. It also connects to future projects: the M4-M5 Link, M6 extension and Sydney Gateway into Sydney Airport and Port Botany (opening 2023). The tunnels are marked for two lanes in each direction, with capacity to add a third.

The M8 is electronically tolled with no cash tollbooths. Linkt accounts and passes can be used to pay for WestConnex M8 tolls. To pay for your travel, open a Tag account, a Tagless account or buy a Sydney Pass.
