Associated works included a northern extension of Westall Road from Rayhur Street, Springvale to Princes Highway in Clayton. Westall Road from Heatherton Road to Centre Road consisted of a two lane undivided road while the road from Centre Road to the Princes Highway was constructed as a six lane divided road. In order to enable Westall Road to truly serve as a high capacity alternative route to Springvale Road, the level crossing with the Cranbourne / Pakenham railway line was grade separated in conjunction with duplication works to upgrade Westall Road to a six lane divided road between Heatherton Road and Centre Road. These works were completed by April 2001.
