NZ Transport Agency Waka Kotahi | 30 Jul 2025 2:29pm | Canterbury

New Zealand Transport Agency Waka Kotahi (NZTA) is advising road users of work underway in the coming days at sites on State Highway 1 in both North and South Canterbury.   

From tomorrow (31 July), repair work to side panels on the Rangitata River Bridge in South Canterbury will mean temporary traffic lights and a 30km/h speed restriction in working hours from 8am to 5pm. The work is due to continue through until Tuesday 5 August. Motorists can expect delays of up to 15 minutes and should plan their journeys accordingly.

From Tuesday 5 August, there will be stop/go traffic management and a 30km/h speed restriction in place on SH1 between Cheviot and Spotswood (North Canterbury), on weekdays between 6am and 6pm, to accommodate tree removal. These are downed trees from a wind event earlier this month. This tree removal work is expected to continue until Thursday 28 August. Once again, motorists can expect delays of up to 15 minutes and should plan their journeys accordingly.

We thank drivers for their patience. People can keep track of the latest highway conditions by visiting our Journey Planner site.
