Build Conventional Bike Lanes Properly
Width: For many years, the standard width for conventional bike lanes was 5 feet. This number is now 6 feet, because wider is safer. However, you should stop there; if a bike lane is 7 feet wide or more, people will try to drive or park in it. Five feet is still a reasonable measure if wider is not possible, especially when a bike lane does not abut parallel parking. In an extreme pinch, it is acceptable to place a 4-foot bike lane between a driving lane and the curb, but that is not an acceptable width for a lane that sits in the door zone.
