I'm stating that the current route has a small part that is not really usable (the short path after the wilder tunnel to get onto Cabrillo Highway that is marked as bicycles=dismount) - a loaded touring cyclist would need to unload their bags, carry the bike up, carry the bags up and load everything again. Special bikes (e.g. tandem, or with two-wheeled trailer) might even be impossible to bring up there.

My comment above was meant to describe a possible alternative. It has the disadvantage of crossing Cabrillo Highway one more time, but is fully rideable instead of the current route.
