MANGAIA'S SYDNEY HARBOUR BRIDGE?!
This road near Tava'enga village was blasted through the makatea in 1951 using war surplus explosives. It was an amazing engineering feat. Before it, bulky goods were carried on horseback up a series of steps. Ewan Smith, in his superb "coffee table" book 'The Cook Islands' likens it to Sydney Harbour Bridge for the way it revolutionised transportation.
