4:00 pm Tuesday, February 17th - Carbon Canyon Road is closed on the Orange County side, due to a rollover traffic collision at the County line just west of Sleepy Hollow. Additional information will be posted as it becomes available.

Traffic does appear to be moving eastbound, however, pretty smoothly through Sleepy Hollow, so there seems to be at least one lane open and there hasn't been a new update yet.
