From midnight tonight there will be a 30km/h speed restriction and lane changes will be in place on State Highway 29 through the Route K toll plaza as the new electronic toll gantry goes live.
The manual toll plaza will no longer be in use and motorists are advised to not stop when travelling through, said the New Zealand Transport Agency.
The road will be restricted to one lane north and one lane south and motorists are advised to drive with care.
The changes will be in place for approximately one month while the toll plaza is deconstructed.
