 | | Approved as chargeable Interstate on 7/7/1947; the portion from Route 101 to Route 5 was originally to have been designated as I-110, with I-10 sharing a route with Route 5 between the San Bernardino and Santa Monica portions of Route 10. |
 | | In 1981, the entire routing was renumbered as Route 110 for continuity of numbering purposes, with the portion S of Route 10 using an interstate shield, and the portion N of Route 10 using a state highway shield. |
 | | Between I-580 and the current Route 61 routing (Doolittle Dr., LRN 226 and LRN 258), present-day Route 13 was unsigned, but was LRN 258 (added to the state highway system in 1959). |
