The Manawatu Gorge will reopen to vehicles this week for the first time since being blocked by a massive slip in August.
The gorge is expected to be open to one lane of traffic on a temporary road in time for Queen's Birthday weekend.
NZTA Palmerston North state highways manager David McGonigal says good progress has been made on the temporary road, which should be open by Thursday, weather permitting.
"This is a really positive development, and we're delighted to be so close to this milestone before Queen's Birthday weekend, and just in time for the arrival of winter. The team have worked their backsides off to get to this point, and it will be a special moment to see the first cars roll through," he said.
"The public's support and patience has been appreciated every single day of the last nine months, and it's been a huge motivating factor for the team as they've battled to get the road reopened."
