Lin estimates that a 150-meter suspension bridge would normally require three or four months to build using a gang of ten engineers. It would cost in the region of NT $ 4 million, whereas the cost of a concrete bridge of similar length at around NT $ 40 million would be over 10 times as much.
據林枝木估計，以一座長度一百五十公尺的吊橋為例，通常十來個人左右的工作班底，工期約需三至四個月，造價在新台幣四百萬元左右；同樣長度的水泥橋，所需經費則至少在四千萬元以上，差距達十倍之多。
