Some of you may have seen the video of the fuel tanker crash in Baltimore. Allow me to say this;

[A HERETIC I AM]

41. "What can be done to keep overpasses safer during icy conditions?"

Outside of heating the road surface in some fashion, not much. I would venture that the Maryland DOT or similar was aware of the situation and it wouldn't surprise me if salt trucks were on the way, but that is little comfort to those already involved.

Weather related multi-car pileups happen all the time, from foggy conditions to white-out to even sand and dust storms.

There is no silver bullet, unfortunately. Lighted signs warning of freezing conditions might help, as well as more use of lighted, changeable speed limit signs that exist in many areas already, the NJ Turnpike being one roadway that has had those for decades. If that tanker driver had more warning, say a mile or two before that he needed to be doing 30 MPH (instead of the 55 MPH normal speed limit) and there were freezing conditions ahead, it would certainly have helped.

But alas, we are not there yet.
