Commuters can expect to drive the entire Waikato Expressway at 110kmh once the highway is fully open mid next year, Waka Kotahi says.
The long stretch of road from Hampton Downs to Tamahere would be one of only two highways in the country that has a 110kmh speed limit.
The transport agency will start consulting on a 110kmh speed limit in September, Waka Kotahi Waikato and Bay of Plenty director of regional relationships David Speirs told Waikato councillors.
The full expressway is due to open mid-2022, and is expected to cut travel times between Auckland and Tīrau by 35 minutes.
There are only two roads with a 110kmh speed limit: the Cambridge section of the SH1 Waikato Expressway, and the SH2 Eastern Toll Link at Tauranga.
