5 March 2026 – Pause on SH1 Ashburton resurfacing

Road resurfacing work on State Highway 1/Archibald Street in Ashburton, that had meant night closures between Hassal Street and Agnes Street (highlighted below), has been postponed.

An update on this work will be provided when the work is rescheduled.

Other SH1 roadworks south of Tinwald, and near Carters Terrace, continue.

4 March 2026 – Ashburton roadworks continuing through to next week 

Recent poor weather is prolonging some roadworks on State Highway 1 in Ashburton.

Road reconstruction work just south of Tinwald, at the Longbeach Road intersection with SH1, which is requiring day-time northbound lane closures and a detour, is still expected to be complete by Wednesday 11 March. However, road resurfacing work on SH1/Archibald Street near Carters Terrace in Tinwald (also referenced in the previous bulletin below), which requires road users to stop on demand and slow for a 30km/h temporary speed restriction, is now expected to continue through to Thursday 12 March.

In addition, from tonight, asphalt resurfacing work on SH1/Archibald Street will mean night closures between Hassal Street and Agnes Street. These closures are scheduled to apply from 9pm to 5am, on Sunday to Thursday nights, through to 5am on Friday 13 March. A detour will be available via Agnes Street, McMurdo Street and Hassal Street during these closure times.

Any further changes will be updated on our Journey Planner site.

16 February 2026 – Ashburton roadworks to impact SH1 travel

Roadworks due to start soon on State Highway 1 in and around Ashburton may mean delays or detours that road users are advised to plan for.

From Sunday 22 February, delays of up to 15 minutes can be expected as resurfacing work is scheduled to begin on State Highway 1/Archibald Street near Carters Terrace in Tinwald, carrying through until Thursday 5 March. Work is due to take place Sunday-Thursday, 7pm to 5am each day, with road users asked to stop on demand and a 30km/h speed restriction at the work site.

There is also road reconstruction work scheduled just south of Tinwald, at the Longbeach Road intersection with SH1, from Tuesday 24 February. SH1 is scheduled to be reduced to a single lane on weekdays through to Wednesday 11 March. From 7am to 6pm, northbound traffic will be detoured via Winslow Westerfield Road and Maronan Road (see map below), and southbound traffic will remain on SH1. From 6pm to 7am, the site will be open to both southbound and northbound traffic, operating under temporary traffic lights. At weekends, both lanes are due to be open but under speed restrictions. Delays of up to 15 minutes apply here too.

Both lots of roadworks are weather dependent and may be postponed/rescheduled. If this happens notice will be provided.  

While the overlap of the two lots of work is not ideal, wet weather so far this summer has impacted the roading programme, and it is important to complete the work within the summer maintenance season. People travelling on SH1 should be aware of the potential cumulative delays. We thank people for their patience and understanding.
