“The lane will remain closed until a crew can repair the entire manhole frame from 1pm today. This is expected to take approximately five hours - including curing time.”
Road authorities said they expected the lane would re-open by about 6pm.
“We understand that this work will take place over peak travel time and we apologise for any inconvenience. However, this is critical work to ensure the state highway remains safe and fit-for- purpose.”
The work comes after an earlier alert this morning - at 7.40am - that the left northbound lane between Ellerslie Panmure Highway and Greenlane had been temporarily closed because of the damaged manhole cover.
Drivers were urged to merge with care to pass the area and to expect some delays until emergency repairs could be done.
An image from a traffic camera showed congestion had built as a work vehicle could be seen stopped near the side of the motorway.
