S.F.’s bike lane expansion rolling along

by Rachel Gordon : SFGate – excerpt

Less than two years after the court allowed San Francisco to implement its ambitious bicycle plan, the city has striped more than 20 miles of new bike lanes, added hundreds more bike racks and made it more difficult to drive down Market Street.

But the efforts, which city officials will highlight Thursday as part of the annual Bike to Work Day event, aren’t without controversy. A lawsuit prevented the city from implementing bike-improvement projects for four years until it studied the potential impacts. Many of the biking upgrades affect motorists with the loss of curbside parking or traffic lanes, or a combination of the two.
