The alignment of the Former Great Western Road at Prospect and its character as an older, two-laned asphalted highway with unformed edges and verges is still clearly evident. This is despite the loss of some sections and changes wrought by the upgrades and construction of the Great Western and Prospect Highways and the M4 Motorway and its approaches. The road is still laid onto, and follows the undulations of, the original landforms as it winds up and over the flanks of Prospect Hill through a relatively underdeveloped former agricultural landscape. At the highest point of the route, just to the west of the intersection with Watch House Road, the views from the road to the Blue Mountains in the west and the Blacktown hills to the north (and to the 1841 St Bartholomew's Anglican Church) are impressive and still convey an understanding of the wider topography which travellers on the road would have experienced for almost 200 years. Long views to the south are now screened by the trees within the Prospect Reservoir surrounds and views to Sydney and to the east flank of Prospect Hill are now diminished by large sheds and infrastructure in the Pemulwuy industrial area.
