The San Francisco Bicycle Program is dedicated to promoting bicycling as a practical form of transportation, emphasizing bicycle safety and improving bicycle routes and facilities. The signs also remind motorists that they are sharing the road with cyclists on an officially designated bicycle route. Loops and spurs have three-digit designations. While the signed bicycle routes often use streets shared with automobiles, whenever possible they take advantage of bike lanes and paths. Bike lanes are strips of roadway marked off from the main road by a painted line.
Bike paths are separate areas set off from the main road.
Lockers and Racks Secure bicycle parking is being installed at various San Francisco locations. Lockers serving commuters in the downtown area are available on a rental basis. Businesses can also apply to have racks installed in public places for short-term bicycle parking. Call the Commuter Hotline for more information on these and other elements of the San Francisco Bicycle Program. The hotline, bicycle locker program and some bicycle route improvements are funded in part by the Bay Area Air Quality Management District's Transportation Fund for Clean Air.
