Beginning Monday, the bicycle/pedestrian path on the right side of the upper deck of the Richmond-San Rafael bridge will be used as a breakdown shoulder lane all day on Mondays, Tuesdays and Wednesdays and on Thursday mornings. The path will then open to bicyclists and others at 2 p.m. on Thursday afternoons; all day on Fridays, Saturdays, Sundays; and select holidays, including Memorial Day; Independence Day, if observed on a Monday; Labor Day; Thanksgiving week from Wednesday afternoon through Sunday night; and the Christmas-to-New Year's week.
