HEAVY traffic being diverted onto the Summerland Way because of flooding has caused monster-size pot-holes to appear.
The RTA has had to arrange urgent maintenance work to be carried out along the Grafton to Casino strip, but said further work would be required because of the large volume of traffic.
An RTA spokesperson said where possible, heavy vehicles were being advised to use the New England Highway instead of the Summerland Way.
“Crews have been constantly deployed to fix the damage as it has appeared and to restore the road to a safe condition,” they said. “The RTA will be reviewing strategies as a result of the 2011 flood event to further improve traffic management.”
The spokesperson said the Pacific Highway was reopened to all vehicles at 3.15pm yesterday.
The RTA said similar to other flood plain sections of the Pacific Highway upgrade, the new crossing of the Clarence River and associated flood plain would have a minimum of a one-in-20 year flood immunity.
