I did the reverse commute today. In the morning at 8:30, both north and southbound 405 lanes were wide open after I passed LAX. Speeds 65-70mph. There was a slowdown between the 110 and the 710 due to a serious injury accident at Atlantic, but that was cleared by the time we got there and traffic flowed fine the rest of the way to Irvine. I was actually surprised how light the traffic was in OC.

On the way back up at 1:30pm it was also wide open between Long Beach and LAX. And of course right at LAX everything came to a halt.
