Location if you're traveling westbound on Adams from Costa Mesa to H.B.: after you cross over the Santa Ana River you start on a slight downward grade. The first traffic light about 200 yards from the river is at Ranger Drive. She was hit just before she got to the light. There's a striped bike lane right there, but it fades out pretty quickly after the Ranger Drive light - you can divert easily onto the Adams Ave. frontage road, then keep going west into the shopping center at the corner of Adams/Brookhurst. There's really no 'bike lane' on Adams as you appraoch Brookhurst, as H.B. restriped the streets to squeeze in another car lane at the intersection; personaly I would never try to 'take the lane' while approaching that intersection as there are too many drivers going between Costa Mesa and H.B. along that stretch of Adams Ave.
