Contractors will complete fibre cable duct repairs on the southbound off-ramp and repair the road surface on the northbound on-ramp This is critical state highway maintenance and essential for keeping these well-used state highway ramps safe and reliable for drivers.

The work will require two separate night closures. These will allow the work to be completed much faster and are deliberately scheduled at night to minimise inconvenience and delays for drivers. 

The closures are scheduled, weather permitting, for the nights of Monday, 25 August, and Sunday, 31 August.

Detours will be required for drivers needing to get in and out of Johnsonville. They will require extra travel time, and drivers should plan their trips accordingly.
