Kauai County Route 520 is 5.1-mile rural highway which serves the community of Koloa. Kauai County Route 520 begins at Hawaii Route 50 (Kaumualii Highway) near Knudson Gap and extends south to Koloa Landing near the southern coast of Kauai. This county route is mostly known for the Koloa Tree Tunnel which is a row of 500 Eucalyptus Trees planted in 1911. What is now Kauai County Route 520 was originally commissioned in 1955 as Hawaii Route 52. Hawaii Route 52 as originally only extended from Hawaii Route 50 south to Hawaii Route 53 at Poipu Road in Koloa.

By the early 1980s Kauai County Route 520 was extended to the vicinity of Koloa Landing and has since had a nominal extension to Hoonani Road.
