NZ Transport Agency Waka Kotahi (NZTA) is advising Canterbury people to avoid travel today if possible, particularly south of Christchurch and around the Waikirikiri/ Selwyn River bridge on SH1, where river levels are rising.

The highway to Akaroa, SH75, is closed due to flooding alongside Lake Forsyth/Te Roto o Wairewa.

Potholes will make for a slower journey between Rakaia and Glenavy, SH1 today. Five crews are working hard today and tomorrow, says NZTA. Expect to see temporary speed limits around sites of deep potholes.

Snow is forecast to affect the road near the summit later today, where 1 to 2 cm of snow may settle at times. Lesser amounts likely lower down.

What should drivers do?

Please slow down, avoid sudden breaking and turning, increase following distances and drive with lights on, is NZTA’s advice.

Wherever possible, people should plan to avoid driving in the worst conditions and keep an eye on weather forecasts and the NZTA Journey Planner to stay up to date with the latest highway restrictions.
