State Highway 1/Waimate Highway near Makikihi in South Canterbury will close between 7pm and 10pm tonight to allow the recovery of a crashed truck.

Detours will be available as the truck is lifted from the roadside, but delays should still be expected.

For northbound traffic, road users can turn left onto Rodgers Road, right onto Sherwood Road, right onto Makikihi Hunter Road and Frederick Street, then rejoin SH1. For southbound traffic, people can turn left onto Makikihi Beach Road, right onto Hook Swamp Road, and then rejoin SH1.

Road users should be aware the detours are on narrow gravel roads and they need to drive with care.

The truck to be recovered tonight was involved in a crash this morning. Police say no other vehicles were involved and nobody was injured.

The timing of the highway closure has been planned to avoid peak traffic flows.
