In this edition of Paper Highways we look at the history of the unbuilt California State Route 93 in the San Francisco Bay Area. The History of California State Route 93 The history of CA 93 dates back to Legislative Routes (LRNs) that were added to the Freeway & Expressway System during 1959.  Specifically the LRNs that would make up the future planned route of CA 93 were as follows: -  LRN 255 west from LRN 107 in Alamo to LRN 235 near Burton. -  LRN 235 west from LRN 255 near Burton to LRN 254 near Moraga.  Note; LRN 235 was added to the State Highway System in 1953 as LRN 233 between CA 17/LRN 69 and US 50/LRN 50.  LRN 233 was reassigned as LRN 235 in 1957 and extended to Concord. -  LRN 254 from LRN 235 northwest along the San Pablo Reservoir to I-80/US 40/LRN 7. -  LRN 254 from I-80/US 40/LRN 7 west to CA 17/LRN 69. The future planned route of CA 93 appears as LRN 255, LRN 245, and LRN 254 on the 1960 Division of Highways St...

CAhighways.org list of Shortest State Highways CA 77 presently has a 13.4 mile portion that has not been constructed.  CA 77 as originally envisioned would have continued northeast towards Concord and would have junctions with; I-580, unbuilt CA 93, CA 24, I-680 and CA 242.  According to CAhighways.org the present route of CA 77 was designated as Legislative Route Number 233 which was approved by the State Legislature in 1953.  The legislative description of LRN ...
