The following table is a list of Kauai roads that used to be numbered state or county highways, or that were assigned route numbers different from their current numbers, matched with the corresponding listings (of current and/or former routes) in the main Kauai route table.
Routes for which there are no "former" segments are not listed below.
. State route;
County route;
Former route;
Other unnumbered route
(Actual county route shields are usually identical to state shields; see the FAQs for
how routes are classified in the listings below. Also, in many browsers letting your mouse linger over a route number graphic will help you decipher it.)
