The M8, St Peters Interchange, and Campbell Road works started construction in mid-2016. The Campbell Road extension and the bridge over Alexandra Canal (Campbell Road Bridge) opened on 22 June 2020, and the M8 and the St Peters Interchange opened two weeks later on 5 July 2020. The M5 East Motorway also became tolled when the M8 opened, after being toll-free for 19 years since its opening in 2001. Prior to the toll, WestConnex had already taken over the operations and maintenance of the M5 East tunnels on 1 May 2020.
