City of Onkaparinga has announced the next round of road closures to facilitate its21 Intersections Road Safety Project in McLaren Vale.

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

Asphalt laying dates have been set for the Chalk Hill Rd / Olivers Rd / Field St intersection, starting from Monday 25 November, subject to weather.

The majority of the works will be completed at night to minimise the impact on local businesses.

Road closure dates and times are as follows:

• Monday 25/11 – Intersection closed 24 hours from 7am to 7am following day.
• Tuesday 26/11 – Intersection closed from 7pm to 7am following day.
• Wednesday 27/11 – Intersection closed from 7pm to 7am following day.
• Thursday 28/11 – Intersection closed from 7pm to 7am following day.
• Friday 29/11 – Intersection closed from 7pm to 7am following day. 
• Monday 9/12 – Intersection closed from 7pm to 7am following day.
• Tuesday 10/12 – Intersection closed from 7pm to 7am following day. 

Shifts scheduled for Friday night and Tuesday night may not be required.

The council says the project, which began in 2023, is on track and all 21 intersections are expected to be completed in June 2025.
