SH1 Waikato Expressway overnight detours via Ngaruawahia


Tie-in works for the Hamilton section of the Waikato Expressway will see an overnight detour and heavy vehicle restrictions next week, Waka Kotahi NZ Transport Agency advises.

The detour will take State Highway 1 southbound traffic via Ngaruawahia while night works are done where the Hamilton section, which is under construction, joins the Ngaruawahia section.

On Tuesday 17 August, all southbound traffic will be detoured from Taupiri to Horotiu between 8pm and 5am. The closure is required to move and extend temporary steel barriers, which provide protection for road workers.

High Productivity and Over-Dimension vehicles will need to use State Highway 26 and State Highway 1B due to the weight restriction at Ngaruawahia’s town bridge.

In the event of poor weather, work will be moved to the next suitable night – August 18 or 19.

The Hamilton section tie-in works will see this detour required from time to time over the next 6-9 months. Most work is being done behind barriers with traffic reduced to a single lane north and south in the works area.

The 22km Hamilton section of the Waikato Expressway opens to traffic next year.

Waka Kotahi thanks motorists for their patience while we undertake this work.
