The Tākaka Hill road will close overnight next week for repair work.
State Highway 60 from Riuwaka to Upper Tākaka will be closed from 9pm to 5am from 22 November to 26 November for pavement works.
Waka Kotahai has asked motorists to plan their travel outside these hours as no detour is available.
Tākaka Hill was extensively damaged by ex-tropical Cyclone Gita in February 2018 and still has single-lane access in parts.
