Detailed inspections will take place in the coming days after a rail bridge spanning a south Canterbury river had one of its 34 piers washed out by high flood waters yesterday morning.
The 610m long Rangitata Rail Bridge is an "important part" of the rail connection between Invercargill, Dunedin and Christchurch, with around eight freight trains crossing each weekday and five each weekend.
Footage provided to 1News shows part of the bridge visibly sagging after the pier was washed out by a raging Rangitata River.
All train movements over the bridge have been suspended due to the damage and rail freight will be managed by road while the bridge is out of action.

KiwiRail chief infrastructure officer André Lovatt said a recovery plan has begun involving key engineering staff, contractors and the local structures team.
"However, work cannot begin until the river recedes from its current high level."
As of 9am on Saturday, the Rangitata River is 2.05m above its normal level.
Inspections have taken place with the use of drones in the meantime, said Lovatt.
"Tomorrow morning, once water levels have receded, we are planning a visual inspection and a further, closer drone inspection."
These inspections will confirm any damage to the bridge spans or piers as well as the repairs needed.
"Safety is paramount and no repairs will be undertaken until it is safe to do so."
