The RTA proposes to construct a truck rest area on the F5 Freeway at Varroville in southwest Sydney. The proposed area at Varroville has been identified as an important initiative to deal with heavy vehicle driver fatigue. The proposal would provide truck parking for up to 60 vehicles. The proposal stretches from approximately 220 metres south of Bunbury Curran Creek to approximately 1 kilometre north of Bunbury Curran Creek on the F5. The purpose of this report is to describe the proposal, to document the likely impacts of the proposal on the environment and to detail protective measures to be implemented.
