I’m not an east bay resident , but viewed from their geographic locations , it would seem that San Ramon will saturate as soon as it opens, with Dublin getting some mild relief from it . Concord would appear to be the one least likely to be filled out at any given time, because it’s at the north end close to the bridge . That also means northbound traffic may skip Concord so as to stay within rush hour bridge toll rates , and instead SC at Napa or Vacaville depending on where they’re headed .
It would be really nice if the pedestals could mount a light indicating whether they’re taken (red) , free but pair taken (amber) or free and not paired yet (green). Really useful when driving into SCs like Dublin where you can’t immediately tell what’s free and taken across two sections , unlike say, Vacaville whee its all in front of you as you drive up .
