A long list of options for a solution to the slip-plagued Manawatu Gorge route is due to come out next week.
The gorge was closed in April after a large slip took out the road, and it may never open again.
The New Zealand Transport Agency has been working for several weeks on a list of long-term, resilient solutions to the problem.
The agency has been engaging with local government, regional stakeholders, industry groups and community representatives, regional transport systems manager Ross l'Anson said.
The list of options will be available for feedback from Monday.
