Drivers urged to plan ahead for roadworks on SH1 Rangiriri


Waka Kotahi is advising drivers to plan ahead for upcoming ramp closures and detours while scheduled road resurfacing is carried out on State Highway 1 along the 4.8km Rangiriri section of the Waikato Expressway.

Update to work schedule for SH1 at Rangiriri, 1 Sept

A wet weather forecast means roadworks at SH1-Rangiriri will not get underway from Sunday evening, 3 September.

The resurfacing work is now scheduled to begin Wednesday night, 6 September, with work continuing until Friday afternoon.

Contractors are skipping to Stage 2/week two of the work schedule (see information below) which needs just the Rangiriri on-ramp south closed. Stage 1 will follow from 10 September, with 3 and 4 remaining as scheduled.

If work can’t start next week then the whole schedule will be put back a week, starting from 10 September.

The month-long investigation and remedial works require three dry days in a week for each of the four stages.

This updates the traffic bulletin below.

From Sunday 3 September, state highway traffic will be managed through the worksite with a single lane in each direction, and a temporary speed restriction of 50km/h in place.

The closure of on and off-ramps is necessary at various times to complete the work, requiring local traffic to use alternative routes.

The work is scheduled to  be carried out in stages over four weeks, starting on 3 September. Day and night shifts will operate from Sunday nights to Thursday nights, with Fridays as a contingency, with dates subject to change depending on weather and other factors.

  • Week 1: 3 September, northbound lanes closed. Rangiriri Interchange off-ramp closed. Use Te Kauwhata off-ramp to leave highway to go to Te Kauwhata, Rangiriri, Glen Murray Bridge.
  • Week 2:  10 September, southbound lanes closed. Rangiriri on-ramp closed. Use Te Kauwhata on-ramp to go south.
  • Week 3: 17 September, northbound lane closed. Te Kauwhata off-ramp closed. Use Rangiriri off-ramp to leave highway to go to Te Kauwhata, Rodda Road, Rangiriri, Glen Murray Bridge.
  • Week 4: 24 September, southbound lanes closed. Te Kauwhata on-ramp closed, Rangiriri off-ramp closed. Use Rangiriri on-ramp to go south, Te Kauwhata off-ramp to exit.

Local drivers are urged to watch out for ramp closures and follow all signage. SH1 travellers are asked to temporary 50km/h speed restrictions, merge early and watch for a changing road layout.

Once the remedial works are completed all lanes will be open to traffic under a 70km/h temporary speed restriction until the final surface is applied next summer. This time is required for the new surface to settle.

Waka Kotahi thanks everyone in advance for their patience while this important work is completed.
