Main Roads Western Australia proposes to reconstruct the existing two lanes into a four lane carriageway at the Bedfordale Hill section of Albany Highway between the end of the existing dual carriageway and the road train assembly area in the City of Armadale.

The earthworks for the proposed carriageway encroach onto Bungendore Park which is part of System 6 Recommendation MSO - Darling Scarp. The proposal also involves the deviation of Neerigen Brook in two locations.
