Claire raises a good general issue regarding Class I versus Class II bicycle facilities. In north coastal San Diego County, we almost lost a near-perfect stretch of Class II (very few intersections, where the road parallels a railroad right-of-way) bikelane on Pacific Coast Highway 101 when construction of a mixed use rail-trail pushed the curb 4 feet / 1.3M toward the centerline of the road. We are supposed to get a new Class II lane soon, but both it and the outer travel lane will obviously be narrower than before. If transportation cyclists had not spoken up, we probably would have lost the Class II entirely, left to enjoy the blissful adventures of sharing a path with alert pedestrians and considerate dog-walkers.
