Background: In New Zealand, large sections of two new bridges -- one railway and one motorway -- collapsed within 24 hours of each other this week.
In the first collapse about one hundred tons (tonnes) of newly-poured concrete crashed from a partly-built thousand foot (300 metre) railway bridge at Mangaweka in the centre of the North Island.
The workers discovered the fault in the moulds used to form stands of the bridge about half-an-hour before the concrete crashed about 200 feet (about 65 metres) into the Rangatikei River.
No-one was injured but it is now doubtful if the structure will be opened in November as planned.
The second bridge collapse was in the country's largest city, Auckland. About 300 feet (100 metres) of a month-old concrete motorway ramp collapsed.
The first signs of a collapse were noticed in scaffolding early on Tuesday (6 May). Scaffolding experts spent all morning trying to rectify the faults.
They left the scaffolding for a meal at midday and the bridge section collapsed three or four minutes later. The other workers on the site were already clear of the area.
