Published on Thursday, 29 October 2026 at 10:35:07 AM

In accordance with Section 3.50 of the Local Government Act 1995, proposed notice is hereby given that the Shire of Serpentine Jarrahdale is required to make permanent thoroughfare changes to:

• Jersey Road at the intersection of Timbrel Road; and
• Timbrel Road, between Jersey Road and north of Charolais Court.

These changes will involve the construction of cul-de-sacs at both locations to facilitate construction of the Tonkin Highway Extension and Thomas Road Upgrade (THETRU) Project, including the northbound Tonkin Highway exit ramp onto Thomas Road.

These changes will take effect from January 2027, following the reopening of Abernethy Road.
