(i-ii) For this 220 km section of road there were four serious crashes, of which one included a fatality.
(iii) Work to realign 3 km of South Western Highway at Thompsons Hill (south of Donnybrook) was completed in June 2022, including an extended overtaking lane.
Since 2022, 6.5 km has been widened south of the Vasse Highway (Pemberton turnoff) intersection. Improvements for the section south of Pemberton, between Vasse Highway and Middleton Road are continuing.
