Two large slips on upper Ohauiti Rd are expected to be fixed and all traffic should be able to pass through in about two weeks, an Inroads spokesperson has said.
Inroads construction manager Brian Crean said they were working on two major slips that had washed out parts of the road.
There was still enough room for traffic to drive around the first slip, about 6km up from Welcome Bay, he said.
A second slip about 12km up the road had taken so much of the road it had been deemed too risky for heavy vehicles to drive on the single lane left, he said.
