Construction works continued in the following years, including around Widgiemooltha in 1929, Scaddan in 1930, and at Higginsville in 1931. From October 1931, work on the northern end and southern end of the road was included as part of the government sustenance work scheme, funded by a federal grant. In 1932 the Red Lake–Grass Patch–Treslove section was worked on, and a portion at Salmon Gums was improved in 1933, with the continuation of the relief work scheme resulting in £5000 being allocated to the road. By August 1933, the whole route was reported to be in reasonable condition, apart from some rough portions between Coolgardie and Widgiemooltha.
