Where did you find a cobblestone road in the San Francisco east bay

Older bits of the docks etc aren’t cobbled? From the Tower in London
downstream get progressively newer dock land areas which largely are
cobbles and are thus in places quite touristy and used for filming and so

Paving stone, baked brick or cobbles are normally just
overlaid with asphalt. As are many Roman stone roads. One
sees the original remnants during excavation work or
trenching but otherwise not.

Vast majority of Roman roads are grandfathers axe/broom, ie been repaired
and rebuilt X number of times, one of the various myths is that they where
stone always, or built always a certain way, one of the of which comes from
a Victorian misreading instructions for a ditch I think it was to mean the
a road.
 Some london roads would have cobbles under them though not all, as hard
surfaces wasn’t uniform until quite late, a large driver of which was bikes
rather than cars.
 But the docks do seemed to have been routinely cobbles even as they got
bigger as ships did, I assume that San Francisco can like London take large
ships still? Or did it move along the coast somewhere?
