The Manawatu Gorge is back in business after a slip forced its closure last week.
New Zealand Transport Agency regional journey manager Delaney Myers said specialists had assessed the site, and it was now considered safe for traffic to use it around the clock.
However, the road past the slip site will remain at one lane with traffic lights and a 30km/h speed limit for the next few weeks.
"We need to keep the lane beside the slip closed until we install rockfall netting to provide extra protection to motorists.
"We also plan to install even more rockfall netting over the next year or two at several locations throughout the gorge.
