"While the full 22km four-lane expressway will open to traffic in July, there is no need to wait until then to open this on-ramp.
"We can't provide an exact date yet for when the expressway opens to traffic but it will be July."
Having the ramp open on June 3 will give people time to get used to it ahead of the planned closure of the nearby Newell Road intersection with SH1-Cambridge Road.
Waikato District Council has decided Newell Road will close the same day the expressway opens in July.
The decision was made at the conclusion of public consultation in 2018. The date for closure was linked to safer options being available when the expressway opened to traffic. The closure will be accompanied by 'No Exit' signage and the intersection will fully disappear when Cambridge Road is upgraded – currently scheduled for 2024.
Tamahere traffic which used Newell Road previously will come and go via the Southern Interchange, using Bollard Road and Alfred Main Drive or Birchwood Lane and Alfred Main Drive.
