Work affecting major highways in Southland and Central Otago is under way and travellers are advised to prepare for delays. Reduced speeds should be expected and parking would not be possible along the highway in front of the tunnel building during this time. Near Cromwell in Central Otago, resurfacing work is planned at the intersection of SH8 and 8B, alongside the Clutha River/Mata-Au, near Dead Mans Point next month. A spokesman for the New Zealand Transport Agency Waka Kotahi said the work would take place from February 9 to 20. The work is scheduled to happen daily from 9pm to 6am, Sundays to Thursdays.
