It is built at the deck elevation of 286 feet over Nanue Stream along the Hamakua Coast on the Island of Hawaii. Nanue Stream Bridge is the tallest bridge on the Island of Hawaii.

Open horizontal concrete rail and cap are placed as parapets. The Nanue Stream Bridge is significant for its association with the Hilo Railroad Company. In addition it is significant for its association with three founders of the Hilo Railroad Company and as a representative example of early 20th-century engineering technology, as well as a source for information about early 20th-century steel manufacture and construction.

Sugarcane was hauled from all over the island to be loaded onto boats in this tiny harbor. A counterweighted pulley system was utilized to lower the cane from the bridge to the boats below. The tsunami from 1946 wiped out the sugar mill on the shore and was eventually removed in 1979. The foundations still remain.
