Major work is now underway on the $560 million Fleurieu Connections package to duplicate Main South Road and Victor Harbor Road.

Night work is being undertaken from 7pm to 7am, and will continue Sunday to Thursday nights until the end of May.

 The work includes installing temporary barriers along Main South Road and Victor Harbor Road.

Once the barriers have been installed, the next step will be the construction of the new duplicated carriageway behind the barriers.

The Department of Infrastructure and Transport says there will be short-term closures along Main South Road and detours on Victor Harbor Road during the work.

They ask drivers to follow the direction of onsite traffic controllers and posted signage.

Local access and freight access will be maintained.

Speed and lane restrictions will be in place.
