Lots of concept details and videos from the Bay Bridge Gateway Park community meeting held in Oakland earlier this month are now available online here:

The three plans are conceptual only, but all of them include increased bike access from both Emeryville and Oakland, as well as a new (potentially elevated) bike path on Maritime Street in West Oakland, and safe connections to the bike/ped path on the east span of the bridge, currently ending on Yerba Buena island.
