Roads in the McLaren Vale region are becoming safer for everyone, with safety improvements being constructed at 21 intersections

Construction commenced in September on the project’s two most significant upgrades, which involve ‘teardrop’ islands at the Main/Johnston/McMurtrie Road intersection and a compact roundabout at the Chalk Hill/Olivers Road intersection.

Upcoming road closures

Chalk Hill Rd / Olivers Rd / Field St, McLaren Vale intersection

Asphalt laying dates are now locked in, with the majority of the works to be completed at night to minimise the impact on businesses within the area.

The following upcoming road closure dates and times (subject to weather) will apply:

  • Monday 25/11 – Intersection closed 7am – 7am following day
  • Tuesday 26/11 – Intersection closed 7pm – 7am following day
  • Wednesday 27/11 – Intersection closed 7pm – 7am following day

Enhanced warning signage has been installed at 14 McLaren Vale intersections.

We have now begun the six-week commissioning process for RJAWS at the following intersections:

  • Seaview Road, Coppermine Road, and Olivers Road
  • Aldinga Road, California Road, and Olivers Road
  • Malpas Road and California Road

These systems will be fully operational by September 2024.


RJAWS will be installed soon at two additional intersections: Main Road, Malpas Road, and Binney Road; and Bayliss Road and Communication Road. This will also involve changing the priority at the intersection.
