30910.8.
(a) Notwithstanding any other law, the department shall immediately, or as soon as practically feasible, but no later than September 30, 2015, implement an operational improvement project that does the following:(1) Temporarily restores the third eastbound lane on State Highway Route 580 that existed prior to 1977 and that was temporarily restored immediately following the Loma Prieta earthquake, from the beginning of the Richmond-San Rafael Bridge in the County of Marin to Marine Street in the County of Contra Costa to automobile traffic.
(2) Temporarily converts the existing one-way bicycle lane along the north side of westbound State Highway Route 580 from the Marine Street
interchange to Stenmark Drive and the toll plaza in the County of Contra Costa into a bidirectional bicycle and pedestrian lane.
(b) The department shall keep the temporary third automobile lane and the temporary bidirectional bicycle lane in place until the department has completed the Richmond-San Rafael Bridge Access Improvement Project (RTP ID 240758) or until construction activity for that project necessitates removal of the temporary lanes.
(c) (1) For the duration of the operation of the temporary third automobile lane, the department shall determine, according to a competent engineering analysis, the maximum speed that can be maintained with safety in the eastbound direction and shall post that maximum speed at appropriate locations. If the department determines that the maximum speed is less than the currently posted maximum speed, then the
department shall, at the time that the temporary third automobile lane is restored, have in place appropriate devices to alert drivers to the lower speed, which may include, but are not limited to, raised pavement markings, flashing lights, temporary electronic message signs, and any other means that the department deems necessary.
(2) For the duration of the operation of the temporary bidirectional bicycle lane, the department shall install appropriate signage indicating that the lane is bidirectional. The department may place a temporary barrier between the temporary bidirectional bicycle lane and the automobile lanes.
(d) Concurrent with the implementation and operation of the temporary third automobile lane and the temporary bidirectional bicycle lane, the department and the Bay Area Toll Authority shall continue, without delay, current efforts to develop and deliver the
permanent Richmond-San Rafael Bridge Access Improvement Project (RTP ID 240758).
