Overnight closure of SH1 at Tamahere next month


Overnight detours will be in place on State Highway 1 at Tamahere, south of Hamilton, on Friday 11 February 2022.

A full closure of the road is required to move traffic on to a new bridge at the Southern Interchange of the Hamilton section of the Waikato Expressway.

The road closures will begin from 6pm on 11 February 2022 while barriers are moved and line-marking done.

The closure points are at the SH1-State Highway 26 roundabout at Hillcrest and SH1-State Highway 21 interchange at Tamahere. The highway will reopen around 6am the following day (Saturday 12 February 2022).

Night-time travellers, especially freight, are encouraged to plan ahead and make use of alternative routes, such as State Highway 1B, State Highway 2-State Highway 27, State Highway 3, State Highway 39 and SH21. These will be highlighted with reminder signs at the outer connections ahead of 11 February.

Detours will be in place around the closure. Local residents will have access at all times, including into Tamahere via Newell Road at the city end and SH21-Airport Rd to the south.

The traffic switch is needed to create construction space for the 22km Hamilton section, which is expected to be completed mid-year.

All traffic will be moved on to the new bridge, which will eventually be the southbound on-ramp, for about six weeks before northbound traffic will return to using the on-ramp into the city.

In case of poor weather or other unforeseen circumstances, work may need to be postponed. People are encouraged to visit the Waka Kotahi NZ Transport Agency Journey Planner website (journeys.nzta.govt.nz(external link)) before they travel for up-to-date information on the road closure and works.

Waka Kotahi thanks motorists for their patience.

Above: All traffic will be using the curved Cambridge Road bridge after 11 February 2022 as work continues on the Hamilton section of the Waikato Expressway.
