Going into my queue for usaca updates is removal of the eastern segment of CA 146 (ca146pin), connecting the eastern entrance of Pinnacles National Park to CA 25. That CA 146 segment once was signed to the former east entrance station for the park, about 2.3 miles from CA 25. Since then, the park has expanded, and the park's website shows the entrance station has been moved to within a quarter-mile of CA 25. A
recent field report (no GMSV confirmation, no camera car has been out that way since the early 2010s) confirms that all route markers and postmiles for ca146pin have been removed. The road may technically remain on Caltrans' books (per the Postmile Query Tool), but since it's unsigned we can go ahead and remove it from the HB.
We could move the deleted ca146pin segment into the usanp route set, but I don't see much point in that. There isn't a lot of pavement in Pinnacles NP, which is set up for hiking rather than driving tours. A network of hiking trails, off-limits to motor vehicles, has long been the only direct connection between the west and east sides of the park.
