Normally it takes me 45 minutes to get from Santa Monica to Santa Clarita. Today, it took me 1 hour, 35 minutes.
15 minutes spent just getting ON the 405 freeway to go north, because for no apparent reason, the 10E-405N interchange was ridiculously backed up.
Then after I finally broke free of that, I got right past the last exit before you go down the hill towards the 101 when traffic ground to a complete halt.
Just under two miles and just over 35 minutes later, I finally passed the source: A flipped-on-its-side pickup truck, along with the Scion that apparently hit it (whose entire front end had been reduced to a six-inch scrunch of metal) and a Lexus that glanced off it with more moderate damage.
The whole thing closed down three of the six lanes of the 405, right before the giant mess of the 405-101 interchange. It was staggeringly awesome.
