New, streamlined Highway 101 carpool lane hours take effect in North Bay

If commuters on Highway 101 in Sonoma and Marin counties are feeling a bit whipsawed these days, that’s understandable.

For the second time in six months, crews for California’s transportation department recently finished updating signs displaying a new set of carpool lane hours for that 52-mile corridor.

As of Monday, revised signs announced that the latest high occupancy vehicle (HOV) lane hours are 6 to 9 a.m. in the morning and 3 to 6:30 p.m. in the evening, in both counties, in both directions, Monday through Friday.
