These works will provide a four-lane highway from Perth to link in with the existing four-lane Southern Outlet north of the Breadalbane roundabout, and a new underpass arrangement to provide safe access to the highway. There will also be an upgraded interchange including an underpass for airport traffic and provision for cyclists.
From Thursday, 15 March 2018 all lanes will be open to traffic for the entire length of the newly constructed Midland Highway between Perth and Breadalbane.
The speed limit will remain 80 km to allow the new seal to bed down and while minor works are undertaken.
For the safety of road workers and road users, please obey all signs, reduce speed limits as required, and follow directions.
Thank you for your continued patience while these works are delivered. Please allow extra time for your journey and be aware of temporary changes to traffic conditions.
