Road repairs State Highway 3 (SH3) Midhirst to Inglewood 6 October to early December 2021

Update: Monday 8 November 2021

Work has now resumed following the pause for the Garden Festival and Arts Trail. The detour for is now reinstated for southbound traffic.

Work at the Durham Road Intersection is now complete, so the intersection is open for northbound traffic.

From October to early December, work to rebuild the road surface will be carried out at a number of sites on SH3 between Midhirst and Inglewood, south of New Plymouth.

To help us complete the work more quickly and reduce delays to motorists a detour will be in place for southbound light traffic while work is carried out.

Light southbound traffic will be detoured from the intersection of SH3 and SH3A in Inglewood, re-joining SH3 at Beaconsfield Road in Midhirst via Tarata, Kaimata and Salisbury roads. Salisbury Road between Croydon and Tariki Rd South will be one lane, open to southbound traffic only.

Southbound freight and haulage will use SH3 via convoy from Durham Road every two hours—as per the schedule below—or State Highway 45.

All northbound traffic will continue to use the state highway as normal but should use the schedule below to plan ahead to avoid delays.

For everyone’s safety, heavy vehicles except those needing to access local roads are not to use the detour route.

All road users—especially heavy vehicles—are encouraged to use State Highway 45 as an alternative route where possible.

The highway will be reopened to two lanes for Labour Weekend and again from Friday 29 October to Sunday 7 November to ensure the successful running of the Taranaki Garden Festival and Taranaki Arts Trail events.

Maintaining your roads

During the 2020/21 construction season we undertook a large programme of work to address as many issues on the Taranaki network as possible.

Thank you for your patience while we undertook this work.

We are currently planning our 2021/22 maintenance programme. In the coming months we will be updating this page with information on this programme.

For information on current road works visit the Journey Planner website.

Please drive carefully through work sites, keep to the temporary speed limits and be respectful of our crews who are working hard to maintain the roads.
