From early 2017 to mid-2019, works were performed as part of the NorthLink WA project to convert the intersection of Reid and Tonkin Highway to the first cloverstack interchange in Western Australia, which also resulted in the access to Beechboro Road North removed (a flyover was built in its place) and the road duplicated to Altone Road. Tonkin Highway was extended north as the carriageway for the new Perth Darwin National Highway. The previous Tonkin Highway intersection was unusual in that Tonkin Highway, which continues as Reid Highway west of the intersection, is the continuous section of the T junction. This allowed those following the road from the west to continue down Tonkin Highway southbound, along with Tonkin northbound continuing into Reid westbound, with those wishing to follow Reid Highway from any direction having to make a direct turn to continue either eastbound or westbound.
