Weather: Several state highways, roads closed as flooding hits Canterbury

Several roads and state highways across Canterbury are closed as widespread flooding and wild weather lash the region.

Timaru, Ashburton, and Selwyn have declared a state of emergency and have evacuated two communities.

The wet weather is causing dangerous river conditions and extensive flooding across the region. Slips and floodwaters are disrupting travel, making some roads impassable and "possibly isolating communities".

Waka Kotahi NZ Transport Agency says the persistent rainfall has closed several state highways. Others are being watched and may be closed if surface flooding continues and as night approaches with reduced visibility.

"Please avoid travelling through south and mid-Canterbury and postpone your trips wherever possible on all these routes," says Tresca Forrester, journey manager for Waka Kotahi.

State Highway closures

  • SH73 linking the West Coast and Canterbury between Springfield/Porter's Pass and Castle Hill due to a bridge approach washout and surface flooding is closed. This route will stay closed overnight and Monday morning at least.
  • SH79 Fairlie to Rangitata due to flooding across the highway and at key culverts/bridges. Closure points are at Claytons Road (Fairlie end) and Earl Road (Geraldine end). This closure will be in place overnight. 
  • SH8 through Burkes Pass is likely to close on Sunday afternoon from Fairlie to Tekapo with culverts constantly filling with debris. 
  • SH77 from Darfield to Methven and Ashburton because there is flooding near Hawkins Bridge. The Selwyn River/Waikirikiri has breached its banks at Glentunnel and is flowing across SH77 to the south. This closure may be extended back to Windwhistle soon.
