Waitaki Bridges Able To Withstand Floods Thanks to Weathered Steel
New Zealand’s Waitaki Bridges are undergoing major changes in order to put to rest doubts the bridges could withstand another flood season.
The 132-year-old single-lane wooden bridges will be replaced by two-double lane bridges, made from weathering steel – a high strength, low-alloy steel that forms a weathered, rusty look.
According to Steve Proud, The New Zealand Transport Agency’s Waitaki Bridges project manager, the $201 million renovation is well underway with a few projects already completed.
Proud believes that by going with weathered steel they are reflecting the heritage of existing bridges while also drastically improving safety.
