I took the above two pictures 5 minutes apart. There's a slight difference between the two shots only because I zoomed the camera slightly differently from one photo to the other. But we just sat there without moving. Once it started moving, we got to a point where one of the five lanes was blocked for 50 feet and there was a construction vehicle and a police car. After that point, traffic flowed easily.
On the way back we could see a police car blocking all five lanes North at the same spot.
While there is a lot on line about this project (the one that closed the freeway totally last July), I couldn't find anything explaining what happened today. There were closures the night of January 25, 2012, but I can't find anything about today.
Then J went to Santa Monica Place to meet four friends she'd gone to kindergarten through high school with. Only one lives in LA and the others were in from as far away as Italy. I dropped her off and then looked for a parking place. All the parking lots were full and there was nothing available on the streets nearby. Half hour later I find a spot about 3/4 of a mile away, parked, and hiked back to the Santa Monica Place.
On the way out, we did get a couple of reminders that of Alaska where traffic is a little easier.
