Researchers testing NZ bridges for earthquake resilience

From Morning Report, 7:52 am on 8 December 2023

A team of researchers in Auckland have been testing New Zealand's bridges - those cookie-cutter concrete ones built by the Ministry of Works in the 1930s and '50s.

Lead researcher Lucas Hogan says they have "beat the snot out of them" to see how they would stand in a large earthquake,  and for the most part, they've performed well.

On Friday, they are conducting the next stage of testing - using steel rods and clamps to further strengthen the structures.

Hogan spoke to Ingrid Hipkiss.
