The NSW Roads and Traffic Authority proposes to upgrade and widen Cowpasture Road between Camden Valley Way and main street Horningsea Park. The proposed works would widen the existing two lanes to a four lane divided road and would link the short sections of the existing four lane road around the intersections of Camden Valley Way and Joshua Moore Drive together and extend the four lane construction north to join the previously designed four lane concept at Main street. This review describes the proposal, documents the likely impacts on the environment and details protective measures to be implemented.
