I-5 will have a complete set of auxiliary routes (i.e. 105, 205, 305, 405, 505, 605, 705, 805, 905), with the completion of [[Interstate 905|I-905]] in [[San Diego County, California|San Diego County]]. Currently, [[Interstate 80|I-80]] and [[Interstate 90|I-90]] are the only two Interstates to have complete sets of auxiliary routes.

Several routes, including [[Interstate 305 (Oregon)|I-305]] and [[Interstate 505 (Oregon)|I-505]] in Oregon, were planned but left unbuilt due to [[highway revolt|local opposition]].
