Example of an old Scotia pole - the upper blue colored crossarm is PG&E's line feeding the town; the yellow lower crossarm is Town of Scotia primary. The Town is decommissioning their own utility and having PG&E take over.

I should also note - I noticed the same painted crossarm setup at the Conoco Phillips refinery in Rodeo, CA. You can drive through there on San Pablo Ave. Easy access off I-80 just south of the Carquinez Bridge
