A temporary reduced speed limit of 40km/hr is in place on the Pacific Highway, from south of Viaduct Road to 200m north of Iolanthe Street, and on the Gwydir Highway between Bent Street and the Pacific Highway. 

In preparation for the start of work on a new roundabout at the intersection of the Pacific and Gwydir highways, barriers will be placed along the highways. Line marking changes will also be made at the intersection to accommodate the barriers.   

Also access from the Pacific Highway to Iolanthe Street in South Grafton will be closed intermittently between 6pm and 6am for pavement, drainage and asphalt work to be carried out on Iolanthe and Spring streets. Work is expected to take three weeks to complete, weather permitting.

Road users will be able to access Iolanthe Street via the new intersection and access road, 400 metres north of the Iolanthe Street intersection.
