|90% of the time little, but high speed, traffic.|
|10% of the time gridlock.|
The SFCTA (SF County Transportation Agency) is doing a Bay Bridge congestion study which will make recommendations on how to deal with the rush hour gridlock. It's a challenge since the Bay Bridge is at capacity during rush hour so the congestion comes primarily from queuing, or storing, cars that will eventually get on the Bridge. No amount of tow-away lanes or turn lanes or even additional traffic lanes will get any cars on the Bay Bridge any faster. The current design tries to solve for less than 10% of the hours a week, and it fails miserably. The other 90% of the time it makes for an unfriendly, and downright dangerous, pedestrian and cyclist experience.
The current design gives people false hope that this is a good way to get on the eastbound Bay Bridge. At the Harrison on ramp seven lanes neck down to one which creates a very slow commute, increases local pollution, and delays MUNI buses such as the 10 and 12 that have routes through the neighborhood.
