The RTA is continuing to upgrade Cowpasture Road from a two-lane road to a four-lane divided road with new traffic signals at key intersections.
Background
Cowpasture Road links The Horsley Drive at Wetherill Park with Camden Valley Way at Leppington. It links new residential areas and employment zones, and provides a regional freight link between Prestons, Wetherill Park and Smithfield industrial estates.
Cowpasture Road also forms an important link to the Westlink M7 with an interchange near Hoxton Park Road. The upgrade will provide improved access for local motorists as well as a safer road environment for all road users.
Cyclists and pedestrians will benefit from new pedestrian and cycle paths with connections to local bicycle networks through the regional park, including the 39km cycleway constructed along the Westlink M7.
