Drivers heading south from the Hibiscus Coast next week will need to plan ahead.

Full overnight closures of State Highway 1 (SH1) between Silverdale and Oteha Valley Road are planned from Sunday 3 to Thursday 7 August.

The NZTA has confirmed the southbound lanes will shut from 9pm to 5am each night for maintenance.

Closures will include the Silverdale southbound on-ramp and the Oteha Valley Road southbound off-ramp.

Detours will be clearly signposted, with motorists advised to use Twin Coast Discovery Highway, East Coast Road and Oteha Valley Road instead.

Weather may impact the schedule, and some ramp or lane restrictions could begin earlier in the evening.

There’s also a separate closure tied to the Penlink project in the same area and time window, adding to the disruption.
