High floodwaters last Friday washed out one of the 34 concrete bridge piers that support the rail bridge over Rangitata River near Canterbury, New Zealand.

The New Zealand rail authority, KiwiRail, is working to correct the resulting sag so that freight services can run once more between Timaru and Ashburton.

It has worked with contractors to divert the flow away from the gap left by the missing pier, which has yet to be located. KiwiRail will build a temporary support and hope to have the line open again by the end of next week.
