Major Intersections
This table reflects the transfer of the State Route 4 Bypass to Caltrans in 2012. Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, and do not necessarily reflect current mileage. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
