Canterbury/ Otago Highways : Akaroa highway reopens, SH1 south of Christchurch shorter detour in place, Port Chalmers highway update, Raes Junction to Milton highway closed

|

While many highways have reopened since yesterday’s peak of the storm, in Otago and South and Mid Canterbury ice has replaced flood water on many routes. Drivers need to take extreme care. Grit has been applied in many places which also requires slower speeds, says Nic Rodger, Maintenance Contract Manager, NZ Transport Agency.

Debris, potholes and broken road edges also require drivers to slow down and treat all areas with caution.

Many families will be returning home from school holiday breaks, so the Transport Agency encourages everyone to take care, accept the journey may take longer, and arrive home safely.

Akaroa to Christchurch highway reopens

The highway between Akaroa and Christchurch, SH75, reopened earlier today, Sunday, but drivers need to expect a slower than usual journey with debris on the road in places.

South and mid Canterbury

There is ice, black ice and some flooding on the highways of south and mid Canterbury so drivers need to take care particularly on bridges and in shady spots. Crews are gritting.

SH1 south of Dunedin

This route is now fully open.

SH1 Dunedin to Christchurch – detour is getting much shorter

State Highway 1 south of Christchurch has had a lengthy Rakaia Gorge/ Darfield detour in place (SH77 and SH73) between Rolleston and Rakaia, but crews have made a shorter detour at Bankside. Drivers should follow signs on the highway around these flooded river areas.

Maia to Roseneath, part of the Port Chalmers to Dunedin highway SH88, two slips closing road

Access between Maia and Roseneath on the Port Chalmers highway (SH88) is closed due to two slips – one at Roseneath and a larger one at Maia. Currently crews are assessing whether there is a detour route for residents as there are slips on access roads.

Crews are working on these slips and hope to reopen the road by the end of the day.

  • People inside the closure area, Maia to Roseneath, can use SH88 to move between the two slip sites.
  • Port Chalmers residents can use Blueskin Rd and Mt Cargill Rd to get in and out of the city.
