Designed by Territorial Highway engineer William Bartels, the Kaahumanu Avenue-Naniloa Drive Bridge is a rigid frame concrete bridge with cantilevered ends that spans a gap in Wailuku’s “Sand Hills” as it carries Naniloa Drive over Kaahumanu Avenue. The Kaahumanu Avenue-Naniloa Drive Bridge achieves state and local significance in the areas of engineering and transportation. The bridge is one of the earliest remaining rigid-frame bridges built in the Territory of Hawaii. The structure is one of two such bridges built in Hawaii in 1936. The bridge represents the advances in engineering technology being achieved in Hawaii during the early twentieth century.
