I drove by the site of this accident a few weeks ago...very sobering. Nothing but a patch of scorched pavement and a makeshift memorial. Just a few scrubby-looking bushes in the median, so it's easy to see why the FedEx rig crossed over with no resistance. The preliminary NTSB report is just a summary of the accident, so no cause yet. I was going to stop and pay my respects, but it's not really a safe place to pull over. It really affected me passing by this spot. I hope someone places a marker or something there. It won't help those affected by the accident, but it would mean something to some of us.
