Numerous questions remain, including access for fans to the waterfront site, which is next to railroad tracks and near the 880 freeway. The team has proposed an aerial gondola to transport fans from Downtown to Jack London Square.

The A’s have yet to acquire the Howard Terminal and Oakland Coliseum sites. Questions about control of the Coliseum site, which is jointly operated by Alameda County and the City of Oakland, also need to be resolved.
