Crossing the Estuary between downtown Oakland and Alameda on a bike requires travel on the extremely narrow and filthy sidewalk in the noisy Posey Tube. Together with BikeAlameda, who prioritized the Estuary Crossing campaign, bicyclists succeeded in gaining an agreement with Catellus (Alameda Landing) and the City of Alameda Transportation Commission to implement an Estuary Water Shuttle (approx 2008-2009). See: rideOn, Jan 2007, "Promising Developments for 2007."
The City of Alameda is also preparing a feasibility study of the options for a long-range Estuary Crossing solution. See: possible solutions.
